The sandbox was very easy to put together. It took 18 50 pound bags of sand. We've had it for 2 months now, and the cover has held up well.  The seats are sturdy and easily support Grandma and Grandpa. It is a quality product, and it is exactly as described. We bought the 5x5, and at this point it is the right size for our toddler grandson.

Pros: Easy to put together and the heavy-duty plastic seems to be color-fast.
Cons: We may have been tempted to buy an 8x8 but that size isn't made. 10x10 just seemed too big for a family sandbox.
