As a writer and a student, this is an extremely helpful product! I just got it in the mail and was able to set it up instantly and start doing my work. My neck already feels better. I haven't tried to adjust the height because the height it came out of the box with is perfect for me, but there are instructions in case I want to change it. I took one star off because you really need an external mouse and keyboard; I have a keyboard but waiting on the mouse to arrive. If you tried to type and click a lot of things using the laptop itself, it would be the tiniest bit shaky. But it is by no means unstable, and the benefit of it is that it is so lightweight. Highly recommend this product, I'm so glad I bought it.
