At $20 it's a relatively cheap option, probably better than a plastic grocery bag (probably with a hole), and nicer than some of the pouches, etc that I've seen that attach to the back of a seat using a strap around the headrest. The fact that it's waterproof is a plus if you have drink containers. Worth $20? Maybe. Making $15k/month on it? Not sure I see that being sustainable. I put this in the same category as the Totasak.
