I have one and have had it for a couple years now. I use it on longer flights over about 4 hours, and it makes coach a bit more do-able. I'm not short at 5'9", but to me makes a difference when my legs are off the floor, even if only inches. It really takes the pressure off the lower back, IMHO. I have a flight next week from LAX-SYD in coach and I will certainly have my Magellan foot rest!^
