Review on Shepherd Hardware 9576 - Enhanced Diameter Capacity by Patrick Ross

I've been using this for about three weeks, apparently to replace a broken office chair caster. That works fine. Can't remember the price but I think it's pretty reasonable. When the package arrived, it wasn't a roller either, but a pack of AA batteries. I called Revain support. The person who responded was able to pinpoint the problem immediately. He sent a FedEx spell overnight and I received it the next day. He told me to leave the batteries.
