Would Not RecommendBattery leakage caused the battery cap to break apart. Every time I've had a battery leak in an electronic I've never had the plastic break. I've always just cleaned it up with alcohol and it was good as new. However, the main reason for 1 star: I tried contacting Klein Tools to get warranty/product support. When I submitted for a Warranty/Support I kept getting: "Error message WRA Requires Return via Authorized Distributor". I could not continue past this step.
Works great

Tool works exactly as described
Would RecommendLove this tool that is quick and easy to use. Best part is you don’t have to touch the wires or receptacles to see if it is hot.

Nice tool
Would RecommendEasy to use and more detailed info than basic circuit testers.
Not very sensitive
Would Not RecommendMy previous detector easily picked up voltage through drywall and switch plates. This one is not very sensitive at all and does not perform nearly as well. It probably performs as well as the detailed instructions indicate (within 1/4”) which is the only reason I didn’t immediately return it. I can only hope I find my old detector that I misplaced.
