Review on ⚡ Enhanced Extech DVA30 Non-Contact Current and Voltage Detector by Nicholas Harrington

These are the only NCVTs I trust and buy. I rarely get false readings, the battery life is great, they're durable, and I've seen a craftsman duplicate the design. The LED is bright enough to be useful without killing the batteries quickly. The only complaint I have is that after I've dropped them a couple of times the battery compartment comes loose and I have to reassemble them. It seems that one turn of the strap keeps it from opening after further falls. I might also add that I probably drop mine 4-5 times a day.
