Seems like a decent little gauge for basic stuff, haven't tried to check accuracy or anything. The NCV (Non-Contact-Voltage) function is a bit weak, you have to get very close to feel anything. What gets those 2 stars is the battery, a tiny 12v thing that almost no one will have around. You take this thing out of the drawer when you need it and find that the battery is dead, you don't use it without going to the store or waiting for the delivery man.
