I am without anciety when leaving myy bike locked somewhere with this one. Im 53" 165 lbs, hippy. Contacted manufacturer directly twice - no reply. The stand was easy to assemble, the only pointer I needed was how to attach the stabilising bar. I would say similar to a magic eraser but more expensive. What a bargain, so pleased I bought two pairs! The parts are finished, but slightly damaged, I received two splinters while assembling even while being extremely careful. Good game to play The 3rd rack is about 6 inches deep and I can now only open the door halfway which bothers me as like leaving it open when not in use to let the some air in. Im not into super-heavy bass, but I do like bass.
