It worked flawlessly and helped me tune my car sound system
That it does what it’s supposed to do. I used it to tune my sound system in my car. I also like that it can be used as a multimeter for fine adjustments or readings because my other multimeter doesn’t read fine units.

Great little scope!
Works well for those times you want to check a signal without getting out a pico and everything. It has worked well for me, the battery life is long and it's pretty simple to navigate the menus. Not quite U-scope quality but for the price you can't beat it.

Signal generator works at 50kHz, solid scope for the money
Solid pocket oscilloscope for $41, but keep in mind that it's a $41 scope. As with most scopes, the controls are confusing until you learn them. It's definitely not the most accurate, but it's a quick and easy way to see a waveform's shape and detect transients. Read the manual to learn how to set it up. It's good for basic automotive diagnostics.The signal generator does in fact operate up to 50 kHz, but as soon as you return to Oscilloscope mode the frequency turns back down to 1 kHz, perhaps due to lack of processing power or perhaps for driving the probe calibration signal. People complaining that the signal generator doesn't work above 1 kHz must be trying to measure the frequency simultaneously using this same device. Also note that the signal generator's actual output frequency is less accurate at higher frequency setpoints, with the most heinous error being an output of 44.4477 kHz at a setpoint of 44.000 kHz (see attached pictures); output is dead-on at 40.0 and 50.0 kHz, though. Signal generator voltage outputs are also not completely accurate (note 2.54V p-p measured at a setpoint of 3.0V p-p).This is good for learning and basic diagnostics, but rely on something more powerful for the high-importance troubleshooting. It can trigger on transients, though.

OUTSTANDING [little] PURCHASE
Beyond happy with this lil' guy. ShOcK & AWE pricing. Lot of bang for very few bucks. Factory box was quite nice, included extras and gr8t presentation. Glad I paid a few extra bucks by going straight to the source instead of a sketchy eBayer. Would purchase again.

Great value for the money, great for experimenters.
An unbelievable value for the money. Nice build quality, easy (Relatively) to use, and unbeatable value for the price. Truly amazing what you can buy for such a reasonable price these days.

Ok for car audio applications.
This is an OK digital scope. It works well for car audio applications, and maybe some signal diagnostics.It is not super accurate with the measurements, but it is good enough for basic stuff.The signal generator is also convenient but basic and also not very smooth.Overall a good value for what it is. Definitively not a high end scope, but functional.
