Review on 🔦 Klein Tools NCVT1P Pocket Clip Voltage Tester Pen - Non-Contact Voltage Detector, 50V to 1000V AC, Audible & Flashing LED Alarms by Jason Sisawang

This thing randomly turns on while I'm driving in my car since it's in my tool bag and it just starts chirping and beeping like crazy. Sometimes it just turns on randomly while sitting on the table without moving it. Then when you want to turn it off, just ignore the button. Also, the pen clip's battery compartment is difficult to operate, you just have to open the damn thing. This sometimes saves you having to change the battery so you don't have to worry about it. Definitely a waste of money, wouldn't want it if it was free. I was so disappointed I don't want to buy Klein again but their ncvt-3 model is so good and doesn't have any of the issues this one has.
