I would recommend this for toddler age children. Small, light children may enjoy jumping. Anyone over 75 pounds may bounce down and feel the ground, even when properly inflated.

Yes, but the blower isn't too loud and wasn't a distraction to the kids when they played in it.

Yes, but you probably want to buy additional balls because I think it only comes with 20-30 balls which don't really create a deep ball pit.

Blown up- approximately 13 feet long by 6 1/2 feet wide. The package-top approximately 1-1/2 ft x 1-1/2 ft square and 2 1/2 feet tall.

We pack it up, but we keep it inside.

Maybe not as big as it appears in picture. One or two toddlers would be perfect. Three or four might be pushing it.

Yes it does... I ordered this and had it shipped to my store. I opened it right there to make sure!
