  1. Eldridge B. (verified owner)

    Item as described. Checked the functionality. All OK. I recommend it.

  2. Nicola S. (verified owner)

    Fast shipping. Looks good quality even though I have not used it yet. Excellent price.

  3. Trevion H. (verified owner)

    Everything as in the description very well packed in styrofoam box. I recommend to everyone and the meter itself is accurate and worth the money. I am already very happy.

  4. Nettie T. (verified owner)

    Convenient tweezers for checking SMD.

  5. Quinten D. (verified owner)

    The order was received without damage. The device came with firmware 1.2 which did not react to diodes at all. The seller sent firmware V1.4 and diodes began to show. However they show no polarity on the probes and ring in both directions. LEDs do not ring at all. I hope fresh firmware will fix everything.

  6. Gregory M. (verified owner)

    Arrived in 10 days well packed in styrofoam box and in original box safely. The LCR-ST1 Mini Smart Tweezers are as described very well made comfortable in hand and have a nice readable display. Will see how it performs in day to day work.

  7. Iliana E. (verified owner)

    An excellent device and addition to a multimeter. Good replacement for expensive devices of the same purpose. The measurements are accurate within the specified limits.

  8. Reagan S. (verified owner)

    Great. Very satisfied.

  9. Marilou B. (verified owner)

    Device fire! All OK but unfortunately sent the wrong set with only 1 pair of tips.

  10. Alf J. (verified owner)

    The goods arrived quickly and well packed first in padding and then in a foam box. I am very satisfied with the device it met my hopes when checking it!

  11. Lesly C. (verified owner)

    A great device. Works fine. Arrived quickly with battery charge at approximately 60%. Package without case and spare metal clips.

  12. Alexanne W. (verified owner)

    Good store fast delivery the goods were in good condition. Overall I am very happy.

  13. Peyton A. (verified owner)

    Well packed. Firmware v1.3. For some reason only one set of probes included.

  14. Kristy H. (verified owner)

    Arrived very quickly well packaged and protected. I have already done tests and it works correctly. Thank you very much!

  15. Adriana S. (verified owner)

    I received the order on time. The equipment follows the innovation and quality profile that FNIRSI has accustomed us to and this is not the first purchase I make of FNIRSI equipment. I recommend it to all colleagues working in electronic board maintenance.

  16. Oren C. (verified owner)

    The box arrived open with one of the tips loose. It seems that someone had already tested it. I tested only if it turns on and selected the language and it seems fine. I have several instruments of this brand and this is the first one that arrived like this.

  17. Mario T. (verified owner)

    For in-circuit measurements not very suitable as the default voltage on the probes is 0.6V. To go to 0.3V takes a few clicks and settings are not saved. With closed probes the readings are not zero and not static. At different frequencies readings sometimes differ by several times.

  18. Orie P. (verified owner)

    Good device for its money thanks.

  19. Ryan G. (verified owner)

    Works and measures. Diodes check not correctly – maybe fixable with firmware. With capacitors and inductors everything is fine. Resistance too.

  20. Dakota S. (verified owner)

    The photo includes additional tips but in fact they are not included.

  21. Emilio B. (verified owner)

    Great product really good quality. I would definitely recommend this seller.

  22. Vito J. (verified owner)

    Package was ordered with bag and additional curved tips but arrived without a bag and with only straight tips.

  23. Teagan S. (verified owner)

    Everything came quickly the product corresponds to the description. I recommend it.

  24. Giovanna H. (verified owner)

    Fast delivery. Accurate measurement. I take it a second time for work.

  25. Guido R. (verified owner)

    Excellent compact device measures additional inductance but does not measure voltage so it is a good complement to the UNI-T UT-116c. By default comes with firmware 1.3 and is easily updated to the latest 1.5.

  26. Lonnie S. (verified owner)

    Packed perfectly as always. I really liked the tester itself – it can show more than most conventional testers for example measuring capacitors with very small capacitance.

  27. Octavia E. (verified owner)

    Everything as in the description excellent product good packaging fast delivery.

  28. Jalon C. (verified owner)

    Seems to be working! A little inconvenient switching and diodes do not register everything plus in-circuit diode readings are unclear. Otherwise a good device. You still need to get used to it as with everything new.

  29. Karianne H. (verified owner)

    Capacitance and ESR measures directly on the board without soldering the capacitor. I recommend it.

  30. Mariam H. (verified owner)

    The first impression is quite accurate the coils show very well.

  31. Dianna H. (verified owner)

    Fast delivery. Precision device. Bought two devices one by one. First for myself and then for a work colleague.

  32. Daisha J. (verified owner)

    Everything arrived well. I recommend removing components for measurement as in-circuit measurements give wrong readings.

  33. Mandy E. (verified owner)

    The shipment was carefully packed and arrived in good condition undamaged. The device according to the description. I recommend the seller as correct and responsive!

  34. Isadore L. (verified owner)

    As always everything is on the level. Checked all functions work. Thanks to the seller for the fast delivery. Recommend!!!

  35. Zoie C. (verified owner)

    Thanks for the order I think it will be good because I haven’t tried it yet.

  36. Coy C. (verified owner)

    Works. Tested electrolytic capacitors shows capacitance and ESR.

  37. Makenzie F. (verified owner)

    The readings are instant. It is very convenient to repair.

  38. Mario M. (verified owner)

    Fast delivery. Precision device. Bought two devices one by one. First for myself and then for a work colleague.

  39. Marc H. (verified owner)

    Not the first time I buy in this store. Product quality packaging and delivery are all at the level. Thank you seller.

  40. Amelie H. (verified owner)

    Tweezers are really comfortable. The tips screws are a bit weak. ESR on capacitors shows which is a plus. LEDs do not light up which is a minus. After calibrating and getting used to it I am satisfied. If they raised the voltage for checking diodes to 0.9-1.0V it would be perfect.

  41. Darren B. (verified owner)

    Very functional and convenient device more than satisfied. Packed just fabulously. Recommend 100%.

  42. Tessie G. (verified owner)

    All OK! Works.

  43. Lexie H. (verified owner)

    No questions about the packaging. But the device disappointed – after a full charge it lasts only 10 minutes at reduced brightness. Maybe I got a defective battery.

  44. Randal D. (verified owner)

    As described. Sent very quickly. Packed very well.

  45. Ruby R. (verified owner)

    Suitable for checking resistors and capacitors. Strange behavior when checking P-N transitions. Diodes with a voltage drop of 0.45V do not ring while a transistor with 0.7V drop rings. Firmware update to 1.5 did not change anything. Packed perfectly arrived without damage.

  46. Misty H. (verified owner)

    For this money the tweezers are cool. Compared with MS8911 the readings practically converge but the MS8911 readings are more stable. FNIRSI readings on resistances below 50 milliohms and capacitors less than 2nF constantly jump. On resistances above 100 milliohms and electrolytic capacitors everything is better. Huge plus is a color display visible from any angle. Diode voltage readings overestimate twice compared to a multimeter. Good for cursory general diagnosis if you do not need super accuracy.

  47. Tommie H. (verified owner)

    All good I recommend.

  48. Eunice S. (verified owner)

    The delivery is fast the packaging is excellent the tester is good the reading is consistent and it is convenient to operate.

  49. Flavie M. (verified owner)

    Very fast delivery. The device is super! I recommend.

  50. Favian B. (verified owner)

    Good device. Only one minus – not all diodes can open with a voltage of 0.6V. But it is convenient to use for in-circuit diagnostics. Delivered very quickly. Well packed. I love it!

  51. Hiram R. (verified owner)

    Diodes measure inaccurately overestimating the voltage drop. ESR depends heavily on frequency and large capacitors only measure correctly at 100Hz. Inductance readings are overstated. If compared to the NW-17 reference tester this is just a toy. Firmware or circuit design requires significant improvement.

  52. Weston M. (verified owner)

    Recommended for beginners. The device detects the parts and displays them.

  53. Lee H. (verified owner)

    The product complies with the description. High quality. Convenient to use. Works great. Measures very accurately! The package arrived quickly and was well packed.

  54. Troy F. (verified owner)

    Very comfortable useful item. I am very happy. Recommend this amazing seller.

  55. Guillermo L. (verified owner)

    Very comfortable useful item. I am very happy. Recommend this amazing seller.

  56. Amelia G. (verified owner)

    Works. A four-wire circuit is organized up to the measuring tips. Not all elements can be checked without desoldering – but to assess the order and find shorts it is quick and convenient.

  57. Meaghan W. (verified owner)

    Good product. Firmware v1.3. Everything works. One big minus is lack of rigidity of the tweezers when compressed making it difficult to keep the SMD component in place.

  58. Brycen R. (verified owner)

    A great pincer multimeter at a very fair price. The device was very well packaged and works flawlessly.

  59. Willis B. (verified owner)

    It has great resistor measurement accuracy and it’s also possible to measure capacitors soldered on PCBs. I fully satisfied with it and highly recommend it to purchase.

  60. Skye C. (verified owner)

    Just fine. Everything measures quickly. Legs convenient for measuring SMD and non-SMD components.

  61. Violette S. (verified owner)

    I did not understand how to make in-circuit measurements. In my opinion it does not work but I bought it mainly for that purpose.

  62. Wilhelmine W. (verified owner)

    FNIRSI LCR-ST1 Mini Smart Tweezer LCR SMD ESR Tester

  63. Keon W. (verified owner)

    The quality is excellent as always with FNIRSI accuracy at altitude. Shop and seller recommended.

  64. Velva H. (verified owner)

    Received very quickly. The product looks very good tested and working as it promises.

  65. D’angelo H. (verified owner)

    Arrived in 2 weeks. Well padded. All whole and unharmed. The order follows the description. The battery in the tester is charged. Works.

  66. Maxine W. (verified owner)

    A great device. Quickly determines the type and value of SMD resistors and capacitors. The probes are sharp enough for very small parts.

  67. Brandyn P. (verified owner)

    Well packed in a foam box the set is complete as ordered. It measures with some errors but for this price it is incorrect to compare with more expensive models.

  68. Amina R. (verified owner)

    Five star sample. Thanks to the whole team at FNIRSI for a great gift to amateur radio operators.

  69. Grant R. (verified owner)

    Great product. A great device. Not precision but with a large set of functionality.

  70. Crawford H. (verified owner)

    The device arrived with a delay of a week. Works perfectly. Recommend.

  71. Magali R. (verified owner)

    A great device. I recommend it.

  72. Bailee M. (verified owner)

    A wonderful device for my purposes.

  73. Ebony L. (verified owner)

    Came discharged and immediately turns off. Only for this 4 stars. Will test later.

  74. Travon F. (verified owner)

    Works. Came with firmware version 1.3 successfully updated to version 1.5.

  75. Deja B. (verified owner)

    I tested it immediately and it helped to find dubious capacitors in the board. The readings were close to those of another ESR device. Satisfied with the device.

  76. Anabel B. (verified owner)

    Fast delivery. Very convenient device for checking SMD components. Packed in a foam box.

  77. Fred D. (verified owner)

    Good measuring device.

  78. Antoinette E. (verified owner)

    Cool device. I checked all the functions they work. Smaller than counterparts in size. Comfortable in hand.

  79. Corrine R. (verified owner)

    Shipped and delivered quickly. The device is convenient with a bright screen and made with high quality. Measurements are adequate only does not determine the polarity of diodes. Possibly fixed in a future firmware update.

  80. Kenny A. (verified owner)

    Product works as expected and description was accurate. Not sure zeroing works though – after the indicated procedure the resistance value is farther away than initial. The display is very good. Wish the probes were more sturdy and there was an option to measure at 100 kHz. Good for fast troubleshooting or generic parts bin identification. Overall satisfied.

  81. Lavern B. (verified owner)

    Fine quality. Firmware update from version 1.3 to 1.5 fixes diode indicator etc.

  82. Angelo S. (verified owner)

    I recommend it works as it should. Like it very much.

  83. Justus C. (verified owner)

    An improvised LCR meter. Not suitable for in-circuit measurements. The device is normal for out-of-circuit use.

  84. Eunice H. (verified owner)

    Be careful: 1. My order was with case and spare curved tips but only the device itself was sent. 2. C and L measurements have acceptable accuracy but ESR value is 2-3 times greater than other instruments and ESR dependence on measurement frequency is not correct. 3. Test signal voltage of 1V is not enough – not all diodes are defined. 4. Even with firmware 1.5 there is no correct calibration algorithm. 5. Unlike M63 there is no instrument protection when checking an uncharged capacitor – there are already examples of burnt devices.

  85. Lavern B. (verified owner)

    Good functional device as described excellent packaging large foam box.

  86. Chandler H. (verified owner)

    Quality product! It takes measurements quite accurately with firmware v1.3.

  87. Elvera P. (verified owner)

    The product is very well packed and works very quickly – you touch it and instantly get the result. The only minus was very long delivery.

  88. Tad L. (verified owner)

    Cool device. Support is good.

  89. Antonette R. (verified owner)

    Item as described. Came with firmware 1.3 updated to 1.5 without problems. Seller recommended.

  90. Stanley D. (verified owner)

    Good device. 5pF capacity showed 4.7pF. About the same with inductance at 10 kHz. Great product.

  91. Louisa K. (verified owner)

    All OK.

  92. Shanna C. (verified owner)

    After initial test decided to update firmware. During the update it hung and did not react to anything. Had to disassemble the device and disconnect the battery to restart. Now it’s working.

  93. Amely F. (verified owner)

    Great instrument. Took it for inductance measurements and it copes with its task perfectly. In general everything is fine. I liked it.

  94. Deangelo K. (verified owner)

    The tweezers began to work much better after cleaning the probe board with alcohol – many traces were from unwashed flux. Now the readings for closed probes when measuring resistance jump to much smaller limits. Cleaning the tips significantly improved accuracy.

  95. Ariane B. (verified owner)

    I just do not know why I had not ordered one earlier. FNIRSI brand is proving to be good quality time and time again. Hard to beat the quality/price ratio. My MBR Smart tweezers (about 300 euros some years back) is going to get some rest mainly due to frequent battery replacements. Many thanks to the company as well as their excellent store.

  96. Hans M. (verified owner)

    Very good and accurate looks strong.

  97. Mose H. (verified owner)

    Received. The quality is good. I recommend the seller.

  98. Ila C. (verified owner)

    The device as an idea is not bad but there are a couple of minuses: very tight tips can strain fingers unlike the DT71 tweezers and it cannot light up diodes. On the whole it is not bad I will test it more in use.

  99. Martine F. (verified owner)

    The tweezers are good make sure to update to v1.5 firmware before using. There are also some changes when measuring on variable voltage.

  100. Jalen M. (verified owner)

    Ordered a minimum package without a case. As a result the seller sent me the full package without surcharge! Many thanks for that! Very satisfied with the device!

  101. Johathan D. (verified owner)

    An excellent tester. The package is complete as on the seller’s page. Readings in different regimes are quite adequate. Came charged and with firmware version 1.3. On the FNIRSI site there is already firmware 1.5.

  102. Alberto C. (verified owner)

    Doesn’t hold the battery at all. For a week in the case it sits at 0%. After a long charge it lasts for a couple of hours. Maybe I got a defective battery.

  103. Shana S. (verified owner)

    Works. There is an error but I cannot verify as I have no reference components.

  104. Lelia N. (verified owner)

    Excellent quality as described. It is very convenient to measure SMD on the board.

  105. Beatrice O. (verified owner)

    Everything works properly as stated. I’m satisfied. The right device for the work. Thank you!

  111. Gordon W. (verified owner)

    Good price and good accuracy but the diode check in V1.3 is bad. Cannot use to check BJTs or diodes. Need to upgrade to V1.5 which I understand fixes this.

  112. Daniel H. (verified owner)

    Looks to be better quality than I was expecting. Haven’t had much time with it yet but seems to work great.

  113. Roland W. (verified owner)

    These are really quite good and I quickly got comfortable with them. For everyday use these are exceptionally good value for money. I’m at the point where I am thinking about these as gifts for some of my friends. I’ve also purchased the tablet oscilloscope purely on the strength of this purchase. I have some great lab-quality gear but 95% of what I need is well served with these tools so I will be recommending these to all my ham radio friends. Congratulations to FNIRSI on a good choice of gear for the average enthusiast.

  117. Sven S. (verified owner)

    The price and quality of the products are very good. However I had already paid $18.05 customs duty when ordering but had to pay another €10.50 customs duty in Germany to receive the parcel. Very annoying.

  118. Cihan A. (verified owner)

    Great.

  119. Fatih (verified owner)

    Very nice and useful product. It would be better if firmware updates were easier to install. Some things are not explained in detail – for example how to perform calibration. A detailed explanation is requested on behalf of all users.

  120. Slobodan P. (verified owner)

    Instrument is great measurement is very precise – compared with professional RLC. Only negative thing was the FW update – received with FW 1.5 and during update to FW 1.6 instrument was stuck at 100%. Needed to open instrument disconnect the battery reassemble and then redo the FW update to 1.6 and then it was fixed.

  138. Blucore (verified owner)

    Truly convenient for testing SMD components down to 0403 size (the tip should be a little more precise for smaller components). This meter is easy to use precise enough and values seem reliable. Good materials and quality of assembly. Will be five stars when the diode function is fully achieved. I recommend it.

  143. Manuel W. (verified owner)

    It really is a useful little tool but it lacks one thing: voltage measurements. It would be really helpful for testing on breadboards and PCBs if this thing could measure voltage across components. One would not have to constantly look from the board to a multimeter and back if single-handed measurements with the display right next to it were possible.

  144. Aldo O. (verified owner)

    I am satisfied with it. Practical handy and quite precise for its price. The only flaw is a small firmware bug: when zeroing the resistance between the tips the difference is added rather than subtracted and this increases with each zeroing. Only by switching the instrument off and on is this reset. For everything else the tool is excellent and practical.

    Equipment especially for checking SMD components before placing them particularly capacitors. There are measurement errors with diodes: silicon diodes measure around 0.5V but fast switching diodes in switching power supplies are measured as resistance not as diodes. Mounted on the board everything shows as resistance. In its favor it has good precision but small inductances in nanohenries only measures in 100 200 etc with no decimal places.

    Easy to use and very accurate. When building projects I use the tweezers to verify resistor and capacitor values or for finding faulty components. Excellent battery life easy to use and very well made. I own lots of FNIRSI tools and find them to be above the competition’s offerings.

    An excellent solution for testing components on a PCB on the fly (which will certainly need to be removed for in-depth testing). Fast and practical.

    Bought other products from FNIRSI. Always on the top.

    Practice shows me in my work with components testing you must use both hands and sometimes it is very difficult. This little device solves that issue and it is very precise and recognized almost all components without problems. I decide to buy more instruments from this company.
