Looks the same as more expensive branded products. You can't beat the price, but I had a problem with a pair of these wheels: they were too loose in their sockets. One wheel kept falling out. Although the solution was pretty simple. The wheels are held in their seats by pressure/friction by a brass ring cut around the shaft. I inserted needle nose pliers into the gaps in the brass rings and used them (in reverse order as spreaders) to expand the rings outward. It only needed a small adjustment and now the wheels are very tight. Without this problem I would have given five stars. It only took one concert to realize that these detachable wheels are essential.
