The best handheld oscilloscope to have under small budget. Using this Oscilloscope for a few months now and it works good and perfectly measures waveforms. It has a good bandwidth allowing us to measure RF signals too. There is no fear in measuring mains voltages because it is handheld and has no ground connection. Downsides: 1. Function generator is tricky to use. 2. Supports only one probe. 3. Trigger mechanism is tricky to use. 4. Non customisable voltage multiplication factor. But overall this Oscilloscope is best for hobbyists and engineers who are looking for an Oscilloscope in small budget.

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

Slick little product. It gets a job done. Not all the jobs maybe, but a job, certainly. The frequency generator is a nice have, and the fact that it will run independent of the scope side is great, and makes it a truly useful piece of test equipment to have. I don't know what the actual adapter is for the cable, but it would be nice to have something a bit nicer than common alligator test clips for signal injection, though, you can always clip it to a dupont cable if needed. Also, the value for cost is absurd. worth double.

Outstanding. Works like a charm.
