I have the Harbor freight one. I hated to buy it because I am sure it is real cheap, anyway we sprung it real bad on the first joint , I started fuming, threw it in the truck and away we went to harbor freight. The sales guy looked at it and said " Huh, that should not have happened, allow me to get you another one" ! So yes we bent the crap out of it, Harbor freight gave us a brand new one, other than the inconvience of haveing to return it the second one did the other three joints just fine and now there are four more joints in line to be replaced. I will add that I am going to use an impact wrench this time instead of a ratchet. I am pretty sure that the impacting helps to break things loose. Good luck
