Has anyone tried the CARES child restraint seat-belt thingie for airplanes? it's crazy expensive if it turns out it's not the bee's knees, and we usually travel with a sit-n-stroll. but i wondered whether this would be a good thing when we have a carseat waiting for us at our destination. i'm hoping that someone in the parenthacks community has tried it so i don't spring for it if it sucks! it looks complicated, and the only testimonials i can find online seem to be, hmm, on their web site.
