It's so nice to pump into these using the Duette, then have one ring that can accommodate either the silicone storage cap or the nipple if you buy that separately. So much less to wash.

we throw all our bottles in the dishwasher and plan to use glass bottles to feed baby with but pumping into glass sounds heavy and uncomfortable. i've been looking for ppsu bottles to pump into and these are perfect!

I am a third time pumping mom and Spectra loyal (thank insurance), so when one of the new Spectra bottles deformed the first time I sterilized it I knew I needed a replacement. I have the old bottles, but this got me interested in more heat resistant PPSU to cut down on plastic risk to my baby.

I love these bottles! I am grateful they fit my Spectra and Maymom flanges. Now I just wish they’d make a larger size so I can level up my baby and accommodate my morning oversupply. Thank you!!!
