Don't pay for renting these year over year for birthday parties. Buy one! This is a great one..it's better than the plainer ones and kids will be more drawn to its spaceship character. It goes up quickly, and down somewhat quickly (hopefully you have a strong husband). It stores really well in the bag it comes in. Just make sure you get a good price by shopping around. You should be paying 2x, maybe 3x tops, the cost of renting a commercial bouncer for a birthday party. Buy a couple balls (large) for the kids to throw around inside.
We inflated this bouncer right away. It had a small (3") rip in it, but it still inflated just fine. We used the patch kit that it came with to fix it and it works just fine. It's great from smaller kids. We even brought it to my parents house and used it in their much smaller backyard. We are so glad that we purchased this and look forward to using from many years to come!
My grandchildren love this bounce house. It entertains them for hours and worth every penny. When you rent a bounce house for a party it costs almost as much as purchasing the item. It stores easily and encourages exercise instead of "couch potatoes".
