Sturdy and cute!
Color: Oak, Size: 22.5"W x 6.5"D, 2Packs, Color: Oak, Size: 22.5"W x 6.5"D, 2Packs
So easy to install. It was my first time using drywall anchors and it was a breeze. Only the middle screw is in a stud and two other screws in anchors. They are very sturdy. Very pleased with this purchase. I bought a second set for our second bathroom too.

These are beautiful. Great choice
Color: Black, Size: 24"W x 6.5"D, 2Packs
I initially had brought these and had to return them, because I brought the wrong size. I returned them and got the correct size. I love them, they are very sturdy and well made. They are easy to install, looks great and the size was perfect too. They are great and are worth every penny. I DEFINITELY RECOMMEND THEM and will be getting another pair.

Decent enough, but needs better anchors
Color: Rustic Brown, Size: 27.5"W x 6.5"D, 2Packs
The included wall anchors are brittle. One out of 8 would shatter just on screwing them into drywall. All of them shatter and strip from driving the screw in.
That said, the bracket holds, and the shelves
are nice for dry locations. Thin fiberboard with thin vinyl veneer, tilted very slightly towards the wall.
Each kit comes with a magnetic level, and each shelf comes with an extra screw, anchor, and securing screw.
Easy to intuit how to install, but includes easy instructions for those who do best with visual examples.
I got 8 shelves and am content with them.
