It takes a little getting used to but I like it so far.
Páraic Ó.F. (verified owner) –
Does everything it claims to pretty well.
Teemu M. (verified owner) –
Overall good. The firmware needs to be fixed – the latest one lost the oscilloscope line and I needed to use older firmware which lacks the ability to upload wave screenshots. But anyway a good device for analyzing.

Even if you have a normal bench top scope odds are you are not taking it around with you. This is a great little tool for the price and really is quite impressive for what it does. Spend the extra money and get the higher end DSO 500 models. These fit right along with my NanoVNA and other small tools for a portable kit.

Very good device.

I’m prototyping power electronics and this little guy has plenty of resolution to measure my kHz range signals. Auto ranging works very well.

I installed the latest firmware 2.0.5 and it is not working. The oscilloscope is not functioning it is very difficult to operate and makes mistakes in voltage values.
Sander J. (verified owner) –
Good product and also great service. Nicely packaged and nice quality. After upgrading the firmware I found a bug and reported it. Within a decent time there was a new firmware version that fixed the issue. It’s hard to find a product with a good price and service like that. I would recommend.

After updating to DSO510 firmware 2.0.5 calibration failed and the device became unusable. I had to downgrade the firmware to V1.0.3. I think there’s a bug in the latest version. Could you please check it?

With the latest firmware 2.0.5 when you press autocalibration every now and then it goes into a loop and doesn’t turn off anymore.
