I found the bed pretty easy to put together. I did pre-drill holes for the slat screws. There is a small crack on the headboard, but it is not noticeable unless you look closely. 
I've slept on it for about a week and am pleased so far. It is sturdy and comfortable.
My biggest issue is, as others have said, the frame is 4 inches wider than my mattress. Not only do the slats show, but I often scrape the back of my calves when I get out of bed in the morning. I don't really get that. Surely they must know the dimensions of standard sized mattresses. 
Otherwise, I'm happy with the purchase.
