This was a MAJOR hit at my son's 5th birthday. Even the grandparents took turns and 3 families insisted I send them the link to purchase one for their house. Then, our church youth group borrowed it and then the kids ministry. It is a HUGE hit. Love the versatility in seating or holding on, the length of the seat and ease of putting up. The price is great. I wish it came with instructions, but a you tube video fixed that problem. A cushion at the end is recommended still, even with the spring break at the end because it is fast. The harness is a great option and even though tiny kids could slip out, we used it to help guide them on the way across (more like from behind to make sure it wasn't to fast and they stayed under control).
