The bolts for the side of one nesting box with the logo didn’t line up, go figure. I had read a lot of complaints about the wheels so I didn’t use them. I was able to complete most of it by myself (older reasonably handy female) but definitely needed help moving it once it was assembled. Strongly suggest using a cordless screwdriver but it went together pretty easily and seems to be pretty sturdy. I’m satisfied with this purchase.
