Well, I assembled the reel and added the rewind mechanism. It sort of works but the spring just doesn't have enough oomph to rewind it. I think that the real problem is that they used lazy Susan bearings in a vertical position and they are just not designed to work in that orientation. They not only have a lot of run-out but that also creates extra resistance that the spring cannot overcome. It may work if I sort of push the hose into the reel to help overcome the resistance but it won't work as intended. I ordered another spring but I think that it may not be as strong as the first one.
