Great shelf
Size: 24in-Shelve
I’m a fan! Good quality, sturdy shelf, very easy to assemble and put on the wall. I recommend having a second person to help hold the shelf while you get the first few screws in, just to keep it level.
I love the larger shelf space, it gives me a lot more storage for the bathroom.

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

If you are working in EMS and you don't have this in your kit, you need to rethink your choices. This has tons of information that is quicker to find than an app. This is my 9th or 10th one in my career. Good information to have.
