Review on GearWrench 3628D 5 Ton Ratcheting Puller by Jon Lewis

I bought this and although I'm not a professional mechanic I'm an engineer who loves to fix my BMWs on the weekends. So I bought it for a rear axle bearing that needed to be pulled out and which I had previously used with a 5 ton OTC puller with no problem. With a 5 ton puller, perfectly centered and as stabilized as possible, I began turning the bolt. I finally got up to drink some water when suddenly one of the legs flew off the squeegee and hit the wall, leaving a huge dent. If I didn't get up, it would definitely hurt me a lot. Sent them back the next morning and ordered an over the counter puller which is actually cheaper. very disappointed with the design of this tool.
