Review on WELWIK Caster Socket Inserts Plastic by Jason Adelaja

Based on my observations these casters are not worth the money for industrial and scientific use.The plastic inserts are flimsy and weak, making it difficult to move heavy objects. Although they might work for light-duty jobs, any heavy usage will result in their breakdown. The only pro is that they are cheap; however, the cons outweigh the pros in this case. Stay away if you need reliable casters for your equipment..
