What Customers Are Saying
Customers overwhelmingly praise this voltage tester for its simplicity, reliability, and compact design. The four-light indicator system provides instant visual feedback without requiring interpretation, allowing users to quickly test outlets, identify open grounds, and verify GFCI functionality. The pocket-sized form factor is ideal for carrying in tool pouches, and its no-battery operation adds convenience. Reviewers consistently describe it as durable and dependable. A few note concerns about probe tip length or GFCI button sensitivity, but these isolated issues do not diminish the strong overall satisfaction and widespread recommendation among DIYers and professionals.

Would Not RecommendThe outlet tester was the only of the three items in the kit that worked. The voltage tester won't do anything and the contactless tester is a dud, too. Real frustrating.
Works well but a little pricey in my opinion.
Would RecommendWill test for multiple voltages however would like to have seen it go below 24 volts to 12 volts.
Very poor range
Would Not RecommendThe range on the contactless voltage sensor is very close; you have to be practically physically touching the right "hot" side of the receptacle to get it to go off. The Harbor Freight version beeps and reacts when its a couple inches from the receptacle. Disappointed for a Klein tool. I gave it to my toddler to play with since is was more useful for that.
