I decided to go the G-Force route, and it just arrived yesterday. I
have to say, I'm very impressed. While I haven't flown with it, I
played stuck it against a glass window and used it a little in the car.
It seems very well made and seems to stick like a glue. I live in
Denver, so I am already at altitude. I think it will be the perfect
solution to my needs.

Thanks for the inpute.
