I've had this jack less than a year. I needed it to fit under my lowered M3, which it did, but the handle always gave me problems. The bent bar wouldn't fit under the car, the socket it nests into deforms until you can't get leverage, and finally, the socket broke off the jack. Additionally, the jack lost hydrolic pressure a couple times and began lowering itself (good thing I had the car on jack stands). I haven't tried to return it yet, but I'm not going to get it replaced. I'm getting a different jack.
I bought this jack to raise my 8x10' shed so that I could improve its foundation. The jack was perfect because the low profile meant that I needed very little room under the shed for the jack. And the amount of lift was sufficient to insert concrete blocks for the foundation. There are two things you should be aware of, the first is that the saddle is not connected so when you transport the jack secure the saddle. The next is that there is a plate that covers the hydraulics that can occasional be dislodged by hitting it. Nether of these issues are critical - just a little attention.
