Excellent test piece of test equipment. There is a product review on Bob Kalpon's YouTube videos where the oscilloscope and test leads bandwidth have been measured. This kind of oscilloscope is highly recommended for signal tracing on power supplies hot area. It becomes as versatile as a multimeter, because let technicians and engineers to get the results of one oscilloscope's test, with the independency of the ground connection. If you ever wonder about how do not blow the oscilloscope because the main lines and the ground wire, the best answer could include to get an oscilloscope like this. One oscilloscope, by the price of a multimeter, fast shipping, well packed, and a test equipment you will always use in the approach of a very low investing, deserves the five stars!
I received the nice pocket oszilloscope within 10 days. It was packed in a series of antistatic bags. After charging the battery, I turned on the device for the first time and it Starts an comprehensive Self calibration. The scope is quite easy to operate, the Auto mode is often sufficient. However, for further setttings I will need to look at the documentation. Overall I recommend the device.
