Like others said in reviews, this took a long time to put together (est. 3 hours). 
I put this together myself and I personally had to use a drill to put most of this together. They show a screwdriver in the instructions, but I was careful and used the drill to help. 

When unboxing I noticed a few imperfections in the wood pieces. (See photos) 
Overall, it’s very nice looking and you only notice the imperfections if you are really looking up close.
