Based on my experience, THIS Industrial and Scientific caster is far below average. The intricate design of the caster claims to provide maximum grip, however, I found it failing to meet even the basic standards. The construction is fragile and fails to cope up with the associated load - making it a bad fit for the material handling industry. The only pro is possibly its striking orange color, but that isn't worth much in the long run... Ultimately, it's one of the worst casters I've used so far..
