Review on Yanavee Adjustable Ergonomic Heat Vent Compatible by Mike Gruwell

It keeps my laptop at the same height as my desktop monitor and is very comfortable. After you adjust it, it will not slip. If you change the height/angle frequently, this probably isn't for you. The hinges are very tight. If you set a height/angle and then just use it at that height, that's a good solution. I don't plan on customizing or moving it, so it's perfect for me.
