Good replacement for harbor freight cylinder. Pay attention to bleeding process for air operation. Thought it was defective at first. Works nice. So far no leaks, woohoo. I would prefer air controller to be metal instead of plastic.
Worked great! Was so impressed I bought a second one. Shipping was fast and packaging was great. I have been using it for over a year now with no problems would highly recommend for any shop or individual use. Saves me much time from hand pumping.
