We bought this dome 4yrs ago. We now have 6 kids the oldest is 9. Every year it is used by our 4 boys and daughter as well as visiting children. It has had at least 8 kids on it simultaneously. We drag it around the yard when we mow, and it never sits on a perfectly level spot. Do I wish it was?  Yes. Do I wish we took better care of it? Yes. But is it doing exactly what it's intended to do despite the abuse? Yes!

For us it has not been a waste (at all) of financial resources to have this in our backyard!
