I am not a professional mechanic but I have bought a few Snap On tools over the years, but no more. About 7 or 8 years ago I bought a $45 test light from one of their dealers. The other day I pulled it out of thr drawer and the coiled wire is allo frayed and comming apart. I left it with a friend of mine at a machine shop on the Snap On route and they tell him no warrenty. This is not my first problem with them they once refused to warrenty a break over bar because it was old.
