Great Product!
Size: 3tiers-Shelves, Size: 3tiers-Shelves
This shelf system is an awesome option if you're looking for an industrial/rustic vibe. It's feels super well made and was easy to assemble. The finish on the wood is fantastic! All the hardware for mounting was there and even if you have minimal experience mounting brackets and hardware to the wall - this was still very easy. I especially appreciated the "U" brackets to secure the wood shelves to the posts - that was an unexpected extra that I was very happy to see included. Unfortunately because of space and the way my wife wanted these spaced, we didn't use the third shelf, but we're definitely going to find some place else in the house to mount that later. Overall, if you like this decor - I would definitely recommend this item!

Great textbook. Well laid out and easy to follow
Format: Paperback
Great textbook. Well laid out and easy to follow. I read ahead before any lectures and while I'm very lucky to have a great professor anytime they teach topics from the book I already have a full grasp from the text due to its useful easy to follow nature.

Well written
Format: Paperback
This textbook breaks down all kinds of the healthcare system we have in the states, and it is easy to understand. A+, but you have to read it and focus.
