The rollers received are just like the ones we removed from the dishrack. We continue to have the same problem with bottom rack running off track. My husband literally has to pick it up full of dishes and place it the rest of the way into the dishwasher or if it starts being pulled out then it runs off track and he again has to pick it up for me. So far we are running a much lighter load of dishes in order for it to function properly. Before I bought these from your store, I spoke to Bosch a gentleman told me that they had redesigned the rollers. I hoped these would be an improved style instead of the old style.
