I have had one of these for about 20 years and it is my primary meter. The graphic interface is nice and the diode test that automatically tests both ways is very helpful.

Holy scope!
5.0
This thing can capture lightning and show you its voltage potential!!! Ok no it can’t. (Disclaimer my lawyers made me do it, do not try to capture lightning with the 440 plus, you will die) but this scope can hold its own, for the price range of this tool, I’m overly impressed. Beats the snot out of a fluke similar tool at darn near 1/4 the price. Are you getting allegiant or fluke quality/ refresh rates/ clarity of frequency bandwidth and noise floor. No, but for the money, and it’s range, it does everything you need to and so much more. If you buy it. You will not be sorry. Just know it does. Charge without being turned on. Past that but one for a friend. They will love it.

Great Features for price
5.0
I have had my unit for over 4 years and have not had any problems. It sees moderate use.
My only complaints for this unit are that the beep for the continuity function isn't loud enough. I also which you could move the window up/down/left/right in oscilloscope mode.
