My new neighbors moved in with 3 kids. Day 4 this appeared in the back yard. Oh no I thought, I don't want to look at that all the time! But it disappeared later that day. After watching them play in this many times, and how the product endured it all, I was sold. When my granddaughter was 3 1/2 I gave this to her for Christmas, despite my son saying they didn't want it, they didn't have room. Now he is sold too, best present ever. They use it in their basement several times a week, all year. It is great exercise. They have had it 2 years this Christmas, the 3 yr. old is now 5 and joined by her little brother.
