Love these!! Be warned they are HEAVY so mounting into a stud is a must. I would have given these 5 stars except for I found hanging them to be challenging due to the fact that the boards have natural variation in shape because they are actual reclaimed wood and not a reproduction. 
Tip use the pry bar part of a hammer to gently pry the wall brackets out, which made it easier for them to catch the shelf part of the bracket. Once I got the two brackets to catch, I used a rubber mallet to tap the shelf down and level it.
