Lisa Taylor –
Use this at work every day, small enough to clip in my pocket. Light is decent and the build feels quality.
Jennifer Brown –
Works fine and bright enough for work. My only complaint is the clip is a little loose, stays in my pocket fine though.
Robert Kim –
I am a contractor and use this daily to check for leaks and stuff. The dual wavelength thing is actually useful, not just a gimmick. Detected a water leak in a bathroom wall that nobody could find. Battery lasts me my whole week. Solid little tool, feels premium in the hand. Def recommending it to my crew.
