These arrived quickly and look great in our new home.  I ended up mounting 2 of them side-by-side, and can now fit a lot of wine storage in a small space...it even looks decorative.  The hardware that comes with the set may be fine to hold the weight of 9 bottles, but I ended up using some more heavy duty toggle bolts at the top just to be safe.  The spacing between bottles is fixed, so an unusually wide diameter bottle will have to go on the top rung (see top left of my photo).
