I really like this hippo and would have given it 5 stars if it were a bit bigger. It's big enough for a large 24 month old to sit in or a small 4 year old. It's very cute and stores well. I use mine as a ball pit for two boys age 2 and 6. However, it would make a nice sandbox for about 100 to 150 pounds of play sand. I would only use it as a pool for a small baby under 2 so toys could fit inside. I recommend it for anyone looking to add to their child's or children's play options.
