This little pocket digital oscilloscope is the cat's meow. After figuring out how the buttons work it does exactly what the advertisements say. One channel scope and function generator, images are sharp and clear. Can upload to computer for permanent storage. Charge via the provided USB cable. Buy and extra one to give to a friend or keep as a spare. I am so pleased!

Pros:- Small and portable- Battery powered- Combined sig gen and oscilloscope features are useful- Decent quality color displayCons:- No measurements or cursors in oscilloscope mode- User interface takes a little getting used to- Cheesy little back / forth / press menu switch on top. Why not make this as the same quality as the front panel keys?- Signal generator has no adjustable DC offset. It's just 0 - [amplitude] Vpp out. That's a basic feature that's assumed on most sig gens._________________Update: I've been contacted by FINRISI to see if there's any technical or product support they can help with. I do really appreciate a company who stands behind their products. I'd gladly shop FINRISI again because of this good customer service.

Works great. It's a bit confusing to operate initially but if you spend some time with it you can figure it out. I use in on my job and appreciate the size of it for traveling.

This oscilloscope is so easy to use in AUTO mode to capture the waveform. I used the scope and signal generator to debug and repair an old analog Moog synthesizer. Being able to produce the various waveforms (sine, square, saw, step, etc.) was crucial to debug the older analog circuitry. I can see so many more uses for this simple yet powerful oscilloscope/signal generator.

This thing is really small, easy to take with you on the go. It works off of battery power, and it's got a nice easily readable display. Overall, for the price it's great!
