My six year-old LOVED this thing, but she was close to the age where maybe she was getting a little big for it. I would say seven or eight is too old. That being the case, I decided to send it back because summer is almost over and I was worried she would be too big for it next summer (bored). The product itself was great, except the sprayer hoses had some funky weird stuff in the nozzle heads that obstructed their proper spray function. We just used a hose to keep the slide wet, and that was fine. The company was fairly responsive to an email requesting a different hose, but during the time I was packing up the hose for shipment to return it, I noticed this product quite a bit cheaper online, by $30. We originally paid $599 which seemed high. In the end, my daughter enjoyed the slide for a few weeks, but we decided to send it back and buy a pool instead (which is more age appropriate). We had to pay to ship it back, which is reasonable, but it wasn't cheap (think: at least eight bucks depending on where you're shipping from). There was one big problem with this jumper slide from a functional standpoint, and that's this: it was a chore to pick it up off the ground every night, and it wasn't easy to store. Leaving it on the ground would've invited mosquitos and dead grass, but we did leave it for a few days at a time. If you buy it, invest in a pool toys caddy, a big one. Otherwise, you've got a huge, heavy deflated jumper laying in your yard, or possibly your pickup truck bed. All in all, this thing would be great for little, little kids, like the three to six range. It's a nice, sturdy, fun, well-made product.
