This toy is so much fun! My 3.5 year old had so much fun jumping and seeing how fast she could jump. She wasn't that great at jumping with 2 feet together until we got this. My 15 month old son even tries to join in the fun. This super skipper does take up a bit of space, but we just use it as a great excuse to get the kids to clean up their toys. We used it outside last summer and worked in the grass. The toy didn't hurt my daughters legs or feet if she didn't jump high enough. I also love that this toy will grow with my kids since there are 3 speeds with beeps to help them figure out how fast to go and also you can adjust how high or low the bars go pretty easily. The entire thing easily comes apart when not in use. Overall we love playing with this and it helps get some energy out.
