Very well made!  We love the thick shelves, definitely not flimsy and the brackets add character!  Each shelf is slightly unique from the other, not drastically, but subtly unique.  We were going to buy floating shelves to avoid the hardware, but we have some rustic farmhouse furniture so we decided the hardware would be a great touch.  They come with long screws ready to hang, but we used drywall anchors just to make sure they would be more secure since they didn’t line up to a stud every time because we bought 6 shelves.  You can also adjust where you want the brackets, meaning they can slide closer to the edge of the shelf, deeper set toward the middle, etc.  Great quality, very happy!!
