Query: Poor design

Main problem: I can't place normal sized mugs on all the arms because there is too little space between each one. Its a pretty major design flaw. I think it would work as designed if you were only hanging expresso size cups.I can't comment on the under-shelf feature as I mounted mine under the cabinet. Last issue is that because its mounted the weight of the mugs causes the side that would otherwise be supported by the cabinet to sag.I would look for a different product if you are interested in hanging more than 4 normal or oversized mugs from the holder.
