We bought this as a birthday present for our 6 year old, as we didn't want to buy something she would grow out of too soon. I did a lot of research, and I chatted online with Blast Zone before making my final decision on what to buy. The inflatable was so easy to set up - there really is no learning curve with this product! We use it in our basement, and we will probably use it outside in the summer. Our daughter uses it alone and with her friends. We couldn't be happier. Now we are considering getting one of the water slides this summer...
