I bought this for my 5 and 3 year old. The 3 year old was really too little for it and couldn’t climb up but this was easily fixed with a foot stool. We deflated the bottom mat that you step on to climb up so we could put the stool down. This slide is so much fun! My kids played for hours. It’s fast too on the little inflatable boards that come with it. If it’s too fast, you can just have your kid slide down without it, which is slower. My 3 year old opted for that. I even went down several times as well. Shot clear over the end of it but had a blast! It’s fun because when you get to the end there’s a big splash from the water collecting at the bottom.
I hope this thing is durable. It came with a couple repair patches in case you get a hole. Just make sure the ground is clear of sticks and rocks and you should be fine.

This slide lasted me a month. I still don’t regret it because it was a month of daily use. Filling it up and picking it up to dump the water out day after day. My kids, other people’s kids, using it over and over again. At the end of the summer we went away on vacation and came back a week later and it was deflated. It has some pinprick holes on it and was a slow but sure leak. I could never find the holes to patch them so I said screw it and threw it away. However, I will be back to buy it again next summer. I know that sounds crazy, $75 for a month of use, but to me that was worth it. It was more engaging than an inflatable pool and it kept my kids out of my house and off electronics every day that month, with no one bugging me to take them to Target or let them watch YouTube or take them to the local water park. They didn’t need those things because they were living their best lives with this slide. This slide brings back the nostalgic 80s feelings of my old banana slip n slide. Not the best quality, but something you will remember for the rest of your life. I’m happy to provide similar memories for my own kids. Buy it. It’ll only last you a summer, but you’ll find it’s well worth it.
