Strong tracer light when it works. Ive only had four months and light started only working intermittently. I can shake or tap sometimes to get working temporarily.

Does what it is supposed to do. I like that guard that spins and blocks switch from being turned on.

The tool works well. The adapter provided is not the correct one. It does not attach to the light source.
