Just acceptable quality: steel bracket is thin and average wheel quality. The caster is not too durable as it has only one ball bearing raceway in swivel head so if overload or by foreign force the bearing ball may fall out.

Quite a bargain. Grey TPR wheel is better than the usual Magenta PVC Caster. It is cushion, tear and wear resistant. With ball bearings and hubs, it creates no noise, requires less labor when operating. The dust proof ring and plastic cover clear the fear of fiber, hair will stuck the wheel. Most suitable on wood tile floor.
