Im always a little concerned about online purchases, but this was a pretty good one. I started with the screwdriver they give you, and it works, but switch to a power screw driver for the littlest screws, at the very least. Those were the most frustrating part of the whole build. Some reviews were saying the pictures werent enough to be able to figure out how to put it together, but honestly just take the time to get all the parts out and get things paired together before you start building, and it goes slow, but smooth. All in all, a sturdy bookshelf. Would purchase again.
