J&S, There is no other! And t the poster who said they use the same bottle jack as the HF/Sears. No way! Maybe it's imported from china, I don't know. What I do know is you'll never find one that operates as smooth and as sure as the one on the J&S plus I don't know if they are warrantied forever but have heard they will replace it forever if necessary.
With the J&S, you can put your bike a foot and a half in the air, roll it all around your driveway/garage, climb on bike and stars it, whatever you want and never tie it down and never a worry!
Try that with one of those others! Definately the best investment I've made. Even my 98 lb wife agrees. Obtw, no problem for her to roll that baby with the bike on it all around the garage/patio... With one hand!

 

I have the same issue with the red one that I have. I never tore into it to see what the deal is with it as I replaced it with a J$S.
