Grandson loves the Toy Story Zing'ems, however the Rocket Rumble playset is NOT something he can play with alone. I would recommend age 5+. When pulling the lever the game lifts up, the zing'ems fly all over the place and the boys get very frustrated. The lever does not stay attached to the playset so they are forever trying to reattached it.
Pros: Durable, flexible play., easy to put together
Cons: no repeat play
My daughter got this with her own birthday money. I wasn't too thrilled, but suprised that she was able to put it together by herself (she's 8) and that she started substituting the "Zing 'Ems" with large marbles, rocks, etc. Very creative! With that being said, it's probably got 3 hours of total play out of it since she bought it 2 months ago.
My 3 year old saw this toy on tv and wanted it so we purchased it for his birthday. He has had hours of fun shooting the toy story characters around the track. It is easy for him to manage and the size is good for storage. The only drawback is that some of the support pieces do not stay in place and need to be re-assembled often.
