“Switched over our flooring to wood floors from carpet and I debated using the metal discs to set the spiked feet on or to use the casters on my two Pangea racks and decided to try the casters. I find myself needing to get behind the racks quite frequently and the casters make it very easy to move the racks away from the walls to make whatever changes I need. I do wish at least two casters in the set had some kind of brake that would help keep the rack from being accidentally moved especially on the rack that has my turntable and that is why I gave it 4 instead of 5 stars. I would recommend these casters to anyone considering them though as I am very pleased with this upgrade.”
