Tester + CB finder + attachment kit to plug tester into light fixtures and directly into wires is typically $50 on sale. Not sure why you'd only want the tester.

Multiple buyers report the tester dying after a few months. At this price that's a tool, not a lifetime purchase.

It has 4.9 stars with a 95% recommendation rate at Lowes. Doesn't really get much better than that. But if you do happen to be one of the very few unlucky ones who receives a dud, the warranty is 2 years.

I have a tester that works identically but is from a different manufacturer. Extremely handy to have; I trust the Klein brand but I can't comment on the quality of this particular item since I don't have it.
