We bought this as a big present for our son's 3rd b-day.  We figured it would be a great thing for all our kids to enjoy for a few years.  

We always used it inside the house and our children are all of the weight limit.  Well, after only 12 months of OCCASIONAL use, many holes began to form and it would not blow up properly anymore.  The patches did not work and now it is inopperable.

We feel VERY dissapointed that it only lasted one year, we were hoping that we were making an investment in a toy that would be around for many years to come.

Our kids LOVED it while it lasted.
