replaceable adapter

love these for my collection cups! these adapters allow me to use my spectra pump and the ledgendairy collection cups together

Works perfect with my Pumpable genie Advanced

Works great with genie advance.

Good for hacking

I use these for my lengendairy cups with my baby buddah. It has helped me with pumping hands free. Would be 5 stars if the thinner tubing would not come loose on the plastic adapter- I’ve lost a few of these since they become looser over use and they are impossible to find.
