If you are a neat freak, this may not be the toy for your family.  I imagine most toddlers don't keep the sand and water separate.  I've heard of some people only using one or the other, which is a good solution.  The drain plug on the water side is a nice feature and if you leave the table uncovered for a few hours, the sand dries out.  The umbrella offers a good amount of shade and the cover is a great bonus.  My son really enjoys the table, and sand and water are inexpensive, so it's not a big deal if half of it ends up on the lawn.
