A 6 year old girl and a 5 year old boy are sitting, lounging, rolling, jumping etc. CONSTANTLY. and these bullets survived it all with no sign of breaking. I've had to refill the air once so far (in over 2 months of indoor use) as it looked a little 'softer' than normal, but otherwise they've been great! Good exercise for kids, helps with balance (and posture when they sit on it and read!). They've used them outdoors in a park, but unless it's dense grassy areas I wouldn't recommend taking the risk of using them outdoors. If you use the included pump, get ready for a "shake the weight" type arm workout, as it doesn't have a check valve - you have to pump hard and fast, then fumble to close it so you can't prevent any more air loss. Nice pre-workout for parents before the kids have fun ;) Definitely recommend for kids under 8 - anyone older may make them too big to enjoy the ball.
