Buy it, try it, and if it isn't so great, save it for when you've got visitors with kids staying for a few days. Give them two $9 closed-cell foam mats and some bedding, a couple of cheap flashlights, help them make some S'Mores on a $5 disposable BBQ grill, and leave the back door to the house unlocked all night for bathroom runs.
When they get home, their friends will get tired about hearing of the great time they had while visiting you.
