At the time of purchase, my daughter was 8 and my son, 2. They both stay entertained with this for long periods of time. We don't always fill up the water side, as my son dumps large scoops of sand in the water, but they both love it when we do add the water. The only thing I might change is the height of it to accommodate seating. My kids end up kneeling or sitting on a bucket to play. I also love the cover it has on it for rainy weather or the winter season. It is easy to put on and take off - my 8 year old can handle it. It has withstood some strong storms without any signs of wear. Overall, it's been a bit of a lifesaver for my husband and me when we do yard work!
