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.

Great quality

Color: Rustic Brwon, Size: 16in

Hassle but they work great. I love the color, the thickness and quality. They do have some weight but in my opinion, I prefer that. Right now the four shelves are holding up my WiFi routers and remotes. Will buy again

Good quality shelves

These shelves are gorgeous in person. Yes, they're darker than the listing pics, but I actually prefer it. The grain is beautiful, they came well-packed, and mounting them was no trouble at all. Now I've got display space that feels both stylish and practical. Definitely worth it!

Easy to install, very tough!

Seriously, scoring these shelf stands for $30 feels like an absolute steal! Four chunky wood boards with metal T-brackets that actually feel substantial - way sturdier than those flimsy IKEA ones I used to have. My old cheapo stands warped after half a year, but these hold up like a champ - I've got like 15 heavy textbooks stacked on them right now. Love the little details too: rounded edges so you won't scrape your hands, and rubber grip strips on the bottom. They look legit fancy in my living room as bookshelves and even class up my kitchen herb garden. My friend thought they were some high-end designer furniture! Honestly, the craftsmanship at this price puts my old $60 wooden shelves to shame. Already told my DIY group chat about these - trust me, you can't go wrong!
