Review on Uxcell Furniture Casters: Premium Threaded Capacity Material Handling Products and Casters by Darrell Beecher

I'm not overweight (5ft 11 inches and 185 pounds or so) and all of these rollers broke one after the other within the first week or so of being installed. I don't sit too hard in a chair. I just rolled forward or backward and TRES, another one broke. It's GARBAGE. Avoid them!
