Easy to put together and stands up well to the hard play of an 18 month old boy!  We have already had hours of entertainment shoveling the sand from one side to the other.  I wish the drain on the water side was a little sturdier as it took him about 2 days to figure out how to open it and drain all the water out.  Also it is inconvenient to have to take the unbrella down every time we take the lid on and off.  Otherwise we are extremely happy with the purchase and look forward to a summer of fun!
