These look great over our loo and provide much-needed extra storage space. I was initially excited to see that drywall-mounting hardware was included, but the wing toggles felt very flimsy and one of them was stripped. Additionally, the instructions tell you to drill 3/8" holes for the wing toggles, but the little "axles" that the toggles pivot upon make them too wide to fit through a 3/8" hole. I wound up using Toggler SnapToggles which have worked well for me on other projects.

Once installed, the shelves have a bit of give when pressing down on them, but not bad for being held up by two metal rods that are anchored to drywall. I liked all the adjustability on the very solid bracket system that allowed for good centering and leveling of the shelves. So, some minor issues but overall a great product.
