Been digging this since I got it last year. Easy to inflate, deflate, fine tune firmness and pack up. Not sure why they added an integrated "pump" to the stuff sack. I don't have the greatest lung capacity and I can get it nearly full with ten deep breaths. I have used it in temps down into the upper 30s with a bag having an EN comfort rating of 35 with no problems.
