Query: Does What It Says

I purchased this to help a problem I was having in my neck and shoulders because my head was tipping to see the notebook's screen. It's working just as expected and I am having some relief in my neck/shoulder area. The gripping material on the top which prevents the computer from slipping holds well. The only drawback is the limited number of choices in adjusting the tilt of the stand.It does just as it says!
