Best collection cups!
The Rumble Tuff Slim Cups are amazing.
Pros:
-easy to assemble/use
-only THREE main pieces
-great suction with BabyBuddha and Spectra
-look fairly normal under clothes and don't get in the way of multitasking while pumping
-perfect capacity for all but my first morning pump
Cons:
-Handwashing gets old, but I get that the dishwasher is hard on pump pieces. The pieces do dry easily and quickly.

Great cups and compatible with my pumps
These work great for making pumping more portable. I prefer a stronger pump and wanted something that would work with my Spectra and pumping at the wall in addition to my Pumpables Genie Advanced. This fit the bill. I can chase around my 1-1/2 year old and pump simultaneously. They are relatively discreet and the insert kit works great. Changing sizes without having to purchase a ton of other flanges. Thanks Rumble Tuff!!!!
