We've had this sand/water table for a year.  I just purchased one for my nephew.  It is a wonderful, well priced product.  There are so many ways to use it.  Sometimes we just put water in both sides, sometimes sand, and sometimes both.  On hot days, we'll even throw in some ice cubes for variety.  The kids can play, standing up, so no sand in the shoes or pants.  The umbrella is a nice touch, so that I know they are protected from the sun.  My very active boys will play for hours together.  It is low enough that a toddler can play, but my 5 year old still loves it too.  Great product and well priced!
