I can't review the shelves because I was never able to put them up. Something to be aware of, if there is something missing or defective in the kit, in my case it was the screws/hardware for assembly, the replacement will have to be shipped in from China. This can take up to three weeks, possibly more if there are delays or holidays in there. Also, the box that these come in is pretty flimsy for holding ~10 lbs or so of steel.I returned the shelves for a refund and bought a different set.Item received missing angle bracket hardware. It will be acceptable if only screws. Kes should do a better job on packaging and quality control.Did not come with all parts needed, had to return it!
