We gave this to our son along with the Deluxe Buzz Lightyear costume at Christmas. I inflated the jetpack before wrapping it, and I was nervous it would lose air by Christmas. I am happy to say that, even still, I have not had to add air or re-inflate the jetpack. It's easy for my son to put on and take off himself (he's almost 5) and the elastic straps velcro, so if needed you can undo the velcro instead of sliding the straps over your arms. Although my son often wears his costume without this jetpack, for a price of less than $5, this was a great purchase!
