Overall it works very well. I have doubts about the weight but I use it for about 150 pounds and it splits between two racks. I'm deducting a star for stability and ease of adjustment. I think it would be easy for them to add a ratchet handle for tightening and maybe a slightly larger base to keep it stable. I plan on installing them on 2x2 foot plywood if it's 3/4 plywood for weight and stability because I can't permanently install them on the floor. All in all very good for the price.
