Metal bracket is cheap and bends easily
Color: White, Size: 36"W x 12"D, 1 Pack
Worst shelf I have ever purchased. Waisted my money, do not waist yours. Installed with the anchors the shelf came with and it did not hold the shelf at all. This happened with nothing on the shelf, just trying to install with the directions given. The entire metal bracket bent and now the shelf is completely useless. IKEA would have been a better option. So disappointing

Looks good.
Color: Walnut, Size: 36"W x 12"D, 2 Pack
They look nice. Easy to mount. The level is garbage…throw it away. Pretty light weight. The stability is good as long as the heavier stuff is placed close to the back of the shelf. It price is to high for this product. Take about $30 off and it would be a reasonable price for the product.

Pantry shelves
Color: Oak, Size: 48"W x 12"D, 1 Pack, Color: Oak, Size: 48"W x 12"D, 1 Pack
The shelf is ok. The drywall anchor that comes with the shelf are useless and had to purchase better EZ toggle anchors. Wish the metal bracket was longer so it could hit two studs. Thickness is good. Light shelves. Assembly is fine if you purchase your own drywall anchors, stud screw and have your own level.
