the worst air ratchet i've ever had was the last design ingersol 3/8 with the black plastic covering, first one lasted less then a week, hit the floor once and broke in half, took it back and got another that lasted a month or two this one never did work worth a ****, took it apart found the problem and fixed it so it worked almost as good as the first one, then it hit the floor once and broke in half, i caught the redass and bought a blue point branded ingersol heavy duty that looks like you could use it as a hammer, i think i threw it on the floor and it DIDN'T break in half i still have the **** ingersol in the bottom of my box, thinking about when i get a tig ill weld it up and hit the pawn shop or ebay with it, see if i can get a pack of gum for it
