I like the portable laptop stand from RioRand. It is lightweight, made from aluminum, and it is sturdy. There is a carry case to bring this on-the-go, making it great for class or travel. There are three adjustable heights, and I personally would prefer one more, lower to the ground, as I do not prefer the larger angles personally. The other caveat is that larger laptops will not fit into the holding grooves properly, allowing the laptop to jostle and possibly slide or fall out of the stand. My kids thick Chromebooks do not fit properly, but my Lenovo does. Being said, I really like this stand despite the few changes I would make.
