The shelves themselves are fine(only opened one so far )hope the rest are OK. By mistake I placed the order twice. I asked if I could return the 3 extra and was told I could but had to pay S&H. I don't like that. What will I do with 3 extra shelves ( I know what your thinking ). Your checkout system is confusing. Also, before I placed this order, I checked reviews from previous customers. Several said they had a problem mounting shelves to wall as mounting screw were not provided. I had the same problem. Had to make 2 trips to hardware store to find the correct flat head screws. HINT, maybe you should make it easier to mount if you provided the correct screws. Another HINT, checkout the checkout system amazon and ebay use. It's pretty good.
