My 13 year old inflated one of these balls super easily. It was an immediate hit with playing four square, which is the primary reason we bought it. After serveral rounds of play over a few weeks, the ball is still inflated. It bounces great. Much better than any other ball we have had. The only test left it if it can handle the trees when we play kickball (hard kicks usually fly up into the woods and pop). I’ll update once we’ve played, but so far we’re happy.
Is this the best ever train set? No. But I gave it 5 stars because I needed an affordable set for a 3 and 5 year old to play with, and this is exactly what I was looking for. They broke one side of the bridge pretty quickly but it’s easily hot glued back together. Otherwise this set is perfect for little kids who just want something to push their trains around on. So if that’s what you need, give this set a try!
