FNIRSI1013D Oscilloscope - Handheld Tablet Oscilloscope, Portable Digital Storage Oscilloscope Kit 2 Channels 100Mhz Bandwidth 1GSa/s Sampling Rate 7" TFT LCD Touch Screen

Overall this is a great tool, using it to set amplifier gain and learn about some other electronics. Battery life has held up pretty well so far, charges with a USB-C. There is a small learning curve but overall the ease of use is mostly easy.

Great little scope. Been using Tektronix scopes for years and this one was very easy top pick up and start using. The touch screen feature is unbelievably better than my old Tektronix TDS 210. Very easy to navigate and a very well designed user interface.I needed a cheap portable scope fast for a trip and am amazed at what I actually got. This may end up being me go-to scope for almost anything that only needs two channels and 100 mHz.I don't know about the accuracy yet and don't know if it will hold up over time but it feels pretty solid so I think the case can take some abuse if needed.

I found this scope 1013D somewhat useful for troubleshooting some issues with LED lights in the field. But the GUI is non-intuitive and buggy. And I found the triggers to be unreliable.Then I found some nice people have modified the firmware and improved it greatly. Search for the forum on EEVBlog for this scope "fnirsi-1013d-100mhz-tablet-oscilloscope" for the improved firmware.

This is an unbelievably smart way to build a scope! It’s the same display as on similarly priced scopes that include dozens of buttons, and it does the same things just using the touch screen. If you can operate a smart phone or iPad, then you can operate the scope. Play with it a few minutes and you are able to start using it. This is the first fundamentally different user interface for a scope since they were invented, and it really works. The scope performance is pretty standard for this price range, it has all the standard things, and it lack a few: difference of ch1 and ch2, more vertical sensitivity (only goes to 50mV per div), FFT needs scale values for vert and horiz and variable resizing so it can be read when needed. Those are suggestions for next generation improvements. You can’t believe this scope when you carry it around and operate it. Highly recommend.

For the past several years, I have been using a credit card sized 2.8 inch oscilloscope for troubleshooting inside the cockpit of my airplane. I found it extremely difficult to read. Finally, in desperation, I ordered this unit and it is exactly what the doctor ordered. it has a beautiful display with excellent legibility, and it is much easier to control operating modes, sensitivity, time base, triggering, etc. and the credit card sized unit. In addition, the probes are much more robust with honest to God BNC connectors and built-in switch enabled 10 X attenuation For measuring higher voltages. I could not be more pleased!

Great for quick diagnostics. Easy to use. Excellent value. Runs on internal rechargeable. Much more portable than my bench Tekronix. Some minor stray noise.

I noticed a few SW bugs with the product, disappointed that they do not have a easy way to update the firmware. The scope does what it advertises. It was a fun experiment but, I suggest people to spend $100 more for something better.

Won't display signals below about 50 millivolts, and the true bandwidth is only about 30MHz. It's a nice looking little machine and I like the touch screen but this thing isn't quite ready for prime time.
