Love the way these turned out in my office! I connected 3 shelves in a row across the wall to make one long shelf and it looks great!

Nice looking. Not very sturdy. Easy to install.
Size: 40x7 2Pcs, Color: White, Size: 40x7 2Pcs, Color: White
Update: The shelf slopes at about a 45° angle when you put anything more than about a pound on the outside edge of it. Perfectly fine up against the wall. Just seems like the braces inside aren't long enough to really give the stability needed. Bracket is nice and tight against the wall. Had to add braces underneath to hold a small plant, a photo and a small container. Wa sloping more and more each week The shelves look great and we're pretty easy to install. They have a single bracket that is very easy to mount to the wall and get nice and level.. The downside is that the bracket isn't long enough to go between studs. This seems like a pretty simple oversight. I mean why wouldn't you make it long enough to go stud to stud? Secondly and maybe more fatally the bars that go inside the shelf to support them coming out from the wall are significantly shorter than the depth of the shelf. Unfortunately this means the shelf is only supported the first few inches coming out from the wall so there is the potential for a slight lean forward.. The anchors they send are trash. Cheap soft plastic that just tears and bends with a screwdriver. I would suggest spending $2 and grabbing your own anchors from Ace or home Depot. The shelves are essentially made of a high grade cardboard kind of wood. They are not going to support much weight or last for years and years however there incredibly affordable and look nice and easy to install. Long as your expectations are right you'll be happy.

Looks Great with a Couple of Modifications
Turned out nice. I would say for the price, it's great quality and took about 45 mins to assemble, but I was also taking my time and using a screw gun. I wouldn't assemble everything by hand. Maybe to get the machined screws started by hand but everything else use a screw gun or drill. 1 thing to look out for: The light strip has a piece of it's stickers that is longer on the one end. I think that's so you can move the light strip over and then the end with the cord on it can be routed threw the top of the wooden side panel, then down on the outside of the shelf. As you can see in my video, I had to route it down on the inside of the shelf because the part that connects the power cord to the led strip landed right where 2 wood panels need to be screwed together. This might seem confusing in this review, but lay down the light strip 1st and then you might understand what I mean. The way mine turned out is still OK, but as you can see the power button control has to be mounted on the inside and you'll see it. Not a big deal for me, but that's not the way I wanted it to begin with. Also, I hated that the cord was white. I just put a couple coats of black spray paint and it looks a lot better.
