I bought this ratchet a few years back from a buddy I used it for about a year. The issue is when you push the button it works, but when you try to take off a bolt or nut it just vibrates will not turn it. It will turn if you don’t have a load on it not sure if a gear is stripped or what’s going on This is for parts only does not work like it should It does not work PARTS NOT WORKING
