I just assembled the Chateau Tower (w/o swing set). 
I did not have a single problem with the hardware, lumber, or instructions. Which is impressive considering how many components are involved. I did need 30 minutes of of help for a few assembly steps, but I put the rest together easily single handed. 
I was suprised to see that some of the hardware components did not have extras. Most of them do, but a couple extra bolts, washers of certain sizes would have been nice. I didnt lose or strip anything, so it did not matter. But be careful so you dont lose any of the hardware. 
I would give it 5 stars, but I have to see how well it lasts first. 
But my first impressions are great!
