    • Amazing!
I love this little oscope. Great price! Works well for car audio, and the signal generator is awesome for electronics troubleshooting! They make a wireless soldiering pen that’s awesome too! Definitely gonna buy more from these guys and the tech support is on point!

    • Signal generator works at 50kHz, solid scope for the money
Review Image by Madeline Barrientos
Review Image by Madeline Barrientos
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. ... show more

    • Great selection of features for such a low price
Review Image by David
Like most oscilloscopes, it will take some time to get used to the user interface and controls. Once you're familiar with it, the functionality is quite impressive for such a small product! All of the oscilloscope and signal generator functions I tested work well. The screen is easy to read and has adjustable brightness. Overall, I'm very pleased with this device. It's become one of my must-have items in my electrical toolbox. The instructions were not very clear about how to connect the oscilloscope probe and signal generator wires (alligator clamp type). There is a small metal adapter you must connect to oscilloscope probe before connecting it to the left port. The signal generator wires connect to the right port. ... show more

It’s a great product but the adapter is missing from the probe

    • Great Little Troubleshooting Device
This is a great product. It eliminates the need to buy conventional, relatively bulky test equipment (oscilloscope, audio generator) for servicing most audio gear. Shipment was super fast.

    • Oscilloscope and Frequency Generator
A little tricking to learn to use and easy enough. Works well and render good info in the graphing. Great price.

    • Low Quality, Nonsense Software.
Very Low quality. The thing feels like a child's toy it's so light. The electrical connectors are so tight it feels like you'll break them when trying to attach them, and the software was obviously written by someone who's never touched an occiloscope in their lives. In my humble opinion, it's not worth ten bucks, let alone $40. Spend the extra money and buy a used Rigol, you'll be so much happier. ... show more
