Super quiet and slim keyboard
Color: Off White, Style: Battery Powered, Pattern Name: Keyboard
This keyboard is slim, stylish and super quiet! Very easy to set up and use right away without any problems. Seems very durable and I’m sure the battery life could be extended if I turned off the battery after using it but after a month of using it I have not had any issues. I bought the mouse that was recommended to go with it as well. Overall a great purchase.

Easy and sleek!
Size: 10 Inch, Color: Gold
I love the shelves! The gold finish pops on my white shelves. Easy to install, I was off by a half inch on the wood shelves I was using for the brackets but I was able to flip the brackets and use the underside to hold my shelves.

Great shelves! Does lean down in front
Size: 12 Inch, Color: Black, Size: 12 Inch, Color: Black
I'm very happy with these deep shelves. We bought the 12 inch bracket to help my mom keep her eggs (she loves her chickens) from taking over her kitchen counters. It came with all the hardware needed. Even some extras. And the anchors it came with were the kind I like that requires so drilling a hole first because they are pointed and you screw them in. Easy peasy. One negative to note is that going that large without having a brace/crosses section does mean it sagged a bit down on the front. Nothing should fall off but it is noticeable in person. Something to think about. All in all I love the look with the (2) 5/4"x 6" x 6' boards from Home Depot. I wanna do it at my house now. One day.

Pretty but screws are the wrong size
Size: 12 Inch, Color: Black, Size: 12 Inch, Color: Black
I definitely like the look of my shelves with these brackets, but be careful with the provided anchors and screws. The big anchors that you screw into the wall - if they aren’t perfectly flat the bracket will wiggle. Also, the screws and anchors aren’t compatible so you either need to buy smaller anchors or bigger screws so will hold tight. Unfortunately we installed half before figuring that out, so I ended up getting some small L brackets for each side so my shelves would be stable.
