Works well. It took me and a friend a while (about 4 hours I think) to install it and it came with a car lift and the ability to stand under it. I highly recommend just going to an authorized dealer for the installation if you're not mechanical and don't have the patience. However, after installation they worked fine. I had some issues when trying to inflate them, they deflated for some reason. Never understood why. They cheated once when they worked as they should.
