I found this drying rack when I was looking for something to put all the different types of sippy cups on.
It works great for the cups, rings, and most of the nipples.
The larger nipples will fall off, but that is ok because of how the prongs are situated (they just fall into the bottom).
I agree about the draining feature (there isn't one).
I put mine on a lazy susan to help it spin easier because I'm impatient, but you may not feel the need.
I am however looking for a second one with more options because this one does not really work for the pumping mother. There isn't enough places to put the flanges, shields, etc - but I will be keeping this one along side the other one to continue putting kiddo cups on.
