This product came in two big boxes. [...]. Once I got the boxes in my basement it took me a little under 2 hours to put it together by myself.  That includes the time it took to wipe each piece with a wet rag to remove any dust. There were only a few steps that were a little difficult. The green climbing wall, one of the bridge rails and connecting the roof pillars to the roof on the tower took some muscle.  Besides that it was pretty easy.  The screws are easy to put in with a Dewalt type drill.  Just make sure you have the pieces in right/snug before you drill and that your screw is going in straight.  Our 1 year old loves it so far. I have the slide going into a ball pit that I made that holds 4,000 balls. I think this toy will be fun for kids up to about 4 years old.  So far we love it and I think it is a good buy for [$].  It is very sturdy. We have it in our finished basement so I can't comment on how it would work outside.
