Looks nice and are easy to hang, however, I have two complaints. One, I am not sure I would trust 12 full bottles on this thing.  It has internal bracing but looks out together with brads.  Also, it will be impossible to line it up with two studs so you will use drywall anchors.  DONT use the ones it came with as they will only support 10-20 lbs.  I used 100lb anchors and it still makes me nervous. Second, the holes are too small for most wine bottles.  And good bottle will not fit.  Cheap stuff and whites seem to be ok.
