Query: Good Product, But Not Worth $20

I like the product and it does what it claims to do; but if you can find something similar for about $10 or less go for it. It's just two pieces of plastic on a hinge with, for lack of a better word, a little kick stand to give you two different heights. The price is the only reason that it did not get 5 stars. Then again maybe I'm just cheap. Lol.
