Have a harbor freight earthquake 18v 1/2. Have throw, beat, left battery dead for days. Used Impact as a hammer, lol. Shows signs of age but 3 or 4 yrs old and same battery. They’re like $250 I think. When it gives up, I’m going to a DeWalt one. Just my opinion. The Milwaukee just are not better till you get to a 3/4″ drive.
