After reading several reviews for different bouncers I decided to go with this one here. I was planning a birthday party for my 2 yr old and didnt want to rent a huge bouncer for a couple of toddlers! The price is great $40 bucks vs. $80 to rent a big one and serves the same purpose (to jump)! The birthday party was at a park and all who have toddlers know they like to wonder around..... the bouncer kept them occupied for the entire party! The older kids enjoyed watching them and passing balloons in for them to throw around!! All the moms were asking where they could get one and said they would have one at they're next party!!! * Did not lose air. * didnt flip over when kids went to one side. *kids loved it!! *you get to reuse it!! ***note... it did take a while to fill with air- 2 people took turns with a foot pump and I blew the bottom part with my mouth all took about 35 min. - so I would definitely suggest a battery or electric powered air pump! same with deflating!!!!
