We bought this sandbox because we were looking to build one that was very similar but found this one at a really good price. The assembly was fairly easy - about an hour for a person who is comfortable with tools (my husband). The box will fit 4 children - 2 on each side. That works great for us but I could see that being a draw back for larger groups of children. The bench/cover is easy to use and not heavy to lift open and closed - but heavy enough to keep cats out. 
The cedar is good quality, looks sharp and smells great in the backyard with the other landscaping. I would definitely recommend this product!
