Yup, they work fine. I have used mine a ton and it's holding up. You can't beat the price/value. As everyone has said, plan on replacing the front wheel clamp with a ride on type. The Stock unit will hold up a Honda CT90, but not much else. The shipping box is huge and realllllly heavy, so factor in a large pickup to get it, and some help to load and unload the beast.
I decided to unload mine at home by myself and ended up dropping the thing on my foot. Damn it hurt something awful for the longest time!
