I've wanted to purchase this table for awhile and didn't know if my Grandsons would enjoy it, so I held off. Wrong Move! One is 4 years old now and Loves it! I purchase the colored (Crayola) sand at [@] and both my Grandsons are kept busy for hours,They love to build sand castles, run their cars through the sand,fill cups of sand and watch them drain through the funnel. We haven't filled it with water, so I don't know if ours would leak, This is a great product and I'll be passing it on when my grandsons decide they no longer want to use it. It is Indestructible!
