These shelves are perfect for my kitchen! They were easy to install. All the hardware was included. They are durable and sturdy and gave my kitchen wall an instant face lift!

Holes in brackets are not spaced for studs!
Color: White, Number Of Shelves: 2, Size: 67"W x 6.5"D
So the quality of this not great, but good enough and they look nice enough on the wall. However, the bracket holes are not spaced at 16" intervals. WTF? I'm not sure who designed this thing. The molly plugs that came with it look OK, but to play it safe I used a cobalt steel drill bit and made my own holes in the bracket. Easy enough with some wd40. My other pick with this is that the screws to anchor the shelf to the bracket are black and and very obvious... they should have supplied some kind of cap.

Beautiful shelves!
Size: 48 Inch, Color: Natural, Size: 48 Inch, Color: Natural
Since new build homes typically don't come with towel rods this was what I envisioned instead. I purchased the hooks separately. The shelves are perfect! I ordered a 36in set as you see with the cream towels and a 48in set that you see with the green towels. They're not loose but not 100% sturdy. I recommend maybe gluing to the wall in addition to the rest and definitely screwing into a stud. They're easy enough to figure out without the instructions. But I will say they're supposed to be screwed in underneath to the rods but they did not come with an appropriate screw for that so I had to use some I already had on hand.

Nice
Size: 30 Inch, Color: Natural, Size: 30 Inch, Color: Natural
Easy to install..comes with small magnetic leveler which made things even easier! Really nice for the price. Only thing is other than sliding the wood onto the metal brace, there’s only 2 screws that screw wood onto brace so it makes for a slightly wobbly shelf on the brace… although I have 6 screws/anchors holding each brace into the wall so it’s technically quite solid…I’m a bit nervous to keep delicates on the shelves

Great Shelves! Drywall Anchors are the Bomb!
These shelves are very plain as I hoped they would be so as to not take away from the items displayed. The blue is true to the images so I was impressed by that. Word of knowledge: if you do not hit any studs, don’t use the mollies that came with them; use plastic drywall anchors! They work amazingly well!
