Holds out its promises, inflates and deflates quickly, I slept well and the main advice was given by one of the commentators, I found really relevant: wait until the plane reaches cruising altitude to inflate the pillow, as if well inflates the ground, the air expands and risk of bursting the pillow. I had little inflated before take-off to be able to rest on, and am well realized as it was once much more "in the air".
