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.

Matter-enabled High Quality Light Strips
Size: 9.8ft
Great lights. Used these as accent lights behind an entertainment center to avoid harsh overhead lights. Three in total. They put out plenty of light and easy to install and use. Love the Matter integration. Negatives: can’t use the cut portion. Once it’s cut, the extra is useless. Not cheap for a light strip. Purchase if you like the light tech or want Matter integration. You have to guess for “light temperatures” (warm, daylight, etc.). I used a Google search for finding the Hex # to input into light control and fine tune from there Love these and would buy again

Great product, reliable quality!
Size: 9.8ft, Size: 9.8ft
I moved into a new place with wood stairs. There’s a landing step that is invisible at night - it just looks like the floor below the step. Of course, one can only determine a stair to be invisible at night after one misses said stair, falling, twisting ankle and foot, lying on floor cursing and crying for help from the husband at 11pm in the dark. I used painters tape for a couple of weeks. Again, not so helpful at night but there was some distinction. I knew I needed to light this step up to avoid future slips on the invisible step. I love Govee products. I have a Govee metal tall skinny lamp thing which is where I learned about this gummy, straight, light tube that they make. I really did not want the light strips that were cheaper w the separate little lights on them since this was going under a stair and you could see the underside of the stair clearly from our lower living room whilst sitting on the couch. This product was SUPER easy to install. I love that you can cut it to size (though if you need exact I would go with the Govee light strips w the little lights there’s more cut areas closer together). I love that I already have the Govee app and it connected relatively easily (turning things on/off, using airplane mode and unplugging will get you connected). My 2 gripes about Govee… 1. Please figure out how to make strips that you can cut and connect - I want to be able to configure a corner or different shape besides just a straight line. I also want to be able to connect multiple lines to one adapter (I had a cheap one that could do this but I was afraid it would burn my house down). I paid $$$ for a single step and would like to have been able to use the rest of my strip for another step but instead it’s just useless. 2. I wish it dimmed a little more - the 1% is really bright in the dark. This strip is VERY bright. Anyways, love my step and it’s safe to take the painters tape off and have it be a normal step.
