Klein quality control issues
Would RecommendThe product has a scratch/cut the entire length of the plastic housing, while being in a brand new sealed package. It was clearly damaged at the factory before packaging. I'm not going to waste my time returning it for a 4" scratch, but it doesn't make this consumer happy paying for damaged products.

Its bright LCD screen clearly displays voltage levels and wiring conditions, helping identify open grounds, reversed polarity, or faulty connections. With a simple plug-in design, it tests both standard and GFCI outlets safely and accurately.

Good but bulky
Used it to check the receptacles and GFCIs in my new house. Easy and straightforward My only complaint is it's too bulky to fit into some outside receptacles with covers.
