Not Your Average Laptop Stand
One of the things that I always worry about with stands for my computer is how sturdy they will be. If they aren't sturdy, they aren't really worth having. This is super sturdy -- I don't feel any bounce or flex when I work on it. It's also super well made and looks good sitting on my desk. Both of those things make this one of the best stands that I've used. I just wish it were adjustable.

Great Product
Size: 9.25 Inch, Number of Items: 6
These shelf brackets are high quality and very sturdy! They were very easy to install, all hardware was included. The brackets accommodate either a 1" or 2" shelving material thickness. The price point was terrific, I highly recommend these brackets.

The brackets were exactly what I had in mind, and at a much more affordable price than Home Depot. They are sturdy and look amazing!

Nice brackets
Size: 11.25 Inch, Number of Items: 8, Size: 11.25 Inch, Number of Items: 8
The brackets look great and fit a 1x12 board perfectly. They've been installed for a few days and seem to be sturdy.
So far, the only negative is the hardware, as other reviewers have mentioned. Initially, I had some trouble locating the stud and decided to use the drywall anchors. I got one bracket installed and the anchor was already pulling out of the wall.
Overall, I think the brackets are great, but just use your own screws and drywall anchors (if needed).
