Bought this for my 2 and 3 year old and wow do they love it!  Their eyes got pretty wide when they saw it!  I put it together myself (I'm female) and it was pretty easy.  It did take a few hours though.  I found the directions easy to follow and the pieces all lined up nicely (by having predrilled holes in right spots, etc.)  Its roomy enough for 2 children to play in the sand box.  We filled it with 10 bags of sand but you could easily put more in.  The canopy does offer some nice shade when the kids are playing.  Overall, I'm happy with this and so are my children.

Pros: Easy to assemble, 'fun look' for the kids, seems durable so far!
Cons: The one thing that bothers me is that the cover for the sand is like a mesh netting.  So, rain goes right through it and makes the sand pretty wet.  I was hoping to have more of a 'cover' as opposed to a net.
