I bought both the 2 & 3 tier racks.  For the most part they are attractive, but because of the height and depth of the shelves, can only hold up to 3 oz bottles. And since I have so many spices & dry herbs, not necessarily helpful for me in the kitchen, so I use them in the bathroom instead. Seems to work better there. I also sit them on the countertops, however, if the rack becomes top heavy, it does have a tendency to tip over.
