The beads themselves are a bit irregular, which is why I have a slightly lower rating. I returned them to Amazon and bought from Home Depot instead as I wanted to be sure of the most robust long lasting hooks. The adjustable flatform fits the wheels snugly enough not to have lateral movement. They are the best shoes I have ever seen and are my favorite thing to wear. Secondly, PLEASE, for the sake of future buyers, add at least a quarter inch to the upright spreaders. I am reorganizing my office space so this storage tower has been pulled out from its place several times already. I have bought cerave twice & disappointed recommended if you just want a portable Bluetooth speaker Very warm, perfect from that standpoint, snug and very comfortable. Super comfy.
