Great play set. Our kids loved it! Feels very secure and stable when assembled. While instructions say it will take 10-14 hours to assemble, it took me and my husband about 6-7 hours, and several of those hours our 2 and 4 year olds were in the yard with us, ‘helping’. All the pilot holes lined up perfectly and as long as you read and follow directions carefully, assembly went very smoothly. 
I would purchase this again.
