A lot of fun for your money!

 from Summit, NJ– Verified Buyer

Very happy with this purchase - the kids can amuse themselves on this for hours. We can get it all setup in under 5 mins - the blower inflates very quickly, then you just need to make sure it's all pegged down properly. This model has no canopy so resists wind gusts. Having used it about 5 times now, it seems well constructed so pleased with the purchase an would recommend to others.

Absolutely love this super big bounce house!

 from Renton, WA– Verified Buyer

Blast Zone is our favorite bounce house brand. This is our third one. We own Little Bopper (smallest, to be used indoor), Rainforest Water Park, and this one. I was searching for the biggest bounce house by Blast Zone and this is great! It says up to 5 kids, 100 lbs, but during my son's 4th birthday, at one point there were 6-8 kids inside and it still stay up strong. These kids range from 3-9 years old. Even if you don't have many kids to play with it, I still suggest you buy a big bounce house because you don't have to constantly worry kids will bump onto each other. By the way, this bounce house has two entrances. One on the slide, and one on the left side. Both are very large and have a few velcros to close the net together. One downside of having a large entrance is that kids can fall off if they play rough. I do not advice kids to lean on the net too as it will pull down the top and the kids can get stuck.

We also use it for play dates. Kids love it but get tired easily because there is so much room to jump around. After a short break they get back inside. We set up a 16x20 tarp underneath it. If you have more (or heavier) kids jumping inside, I suggest you stake it. The stakes are included. Otherwise the bounce house keeps shifting. It's light, only 60 lbs. It has an escape air chamber, and another long air chamber for inflation. You have to keep the blower running, just like all other bounce houses. It is not noisy, perhaps like a vacuum sound. The kids are noisier.

If you want to make it more fun, go buy some pool noodles and cut into shorter length. Kids will have fun combating each others. I use balloons from my balloon animals supplies and make them swords. You can put a ball in it and they can kick it around too. The slide actually works and that is a plus. My son likes to slide down. It is more fun for shorter / younger kids (5 and below). Taller kids are too tall, so before they slide down their legs already land on the floor.

Deflating it is easy. We like to jump on it and press the air out. We take care of our bounce house and always vacuum it before we fold it. We don't want tiny rocks, sand, grass to damage the surface. I can easily fold this by flattening all the corners and making sure it doesn't have a lot of crease, then fold 1/6 on each side. Keep folding until the two sides meet in the middle and then fold both sides together. I then roll it up starting from the end with the slide. That way you allow air to escape easily through the other side that has the two air chambers. It doesn't fit the bag that comes with it. There is no way you can get it fit inside, it's just too small. Why bother trying to fit it inside when you are just going to take it out again in a few days? Kids can't wait to play with it.
