I kept checking while I was driving to see if it was moving at all, and it didnt budge. The only downside is that there are two configurations on the ford explorers, so you can put the rear rack further back if you need to. This is a solid product and did what I needed it to do which was hold my mops, broom and umbrella. but all of her items seem to be falling off in quality, especially her purses too! I bought this for my children?s Xbox controller &headset. I tried wiping them off the best way I can mfg over-seas, but quality seems quite good. The pad will give you added support, comfort and allow you to push a little bit more. Usually pretty difficult to return the bar on them perfectly. Er kann aber bequem aufgebogen werden, so das er auch noch für Dickschädel gut zu tragen geht.
