When your under a sink fixing, looking for a leak!!!! The moving the light around or flashlight in moth. Nooooo way! Set this up on magnetic platform (sold-separate), way worth the 11 bucks just add to cart. Or for crawls pace attic plumping or HV/AC. Any thing. You can bend snake in a way where 95% that’s it... you won’t need to full with your light again. And as a handy man remodeler Frelux 2 is as good as it gets.
