Review on 🍼 Maymom 21mm Flange: Compatible with Spectra S2/S1/9 Plus Breastpump - Replacement Parts & Accessories by Veronica Ramos

If you want quality parts at a lower price then look no further. I used to buy parts from another non-branded supplier and while they got the job done, Maymom did a better job! The order included two bottles with one-piece travel caps, two backflow preventers, two hoses, two flanges and FOUR duckbill valves that are as massive as the originals. Bottle sizes are the same as Dr. Browns I use. There is a gap between the non-return valves and the flanges, but this does not affect the vacuum. The instructions provided explain best practices to help you avoid and troubleshoot problems. O-rings are also provided in case the flanges are not screwed tightly onto the bottles. I haven't used them and haven't had any problems, although I'm not very mobile when pumping (I use S2 and 9 plus Spectra). I have 10mpp and have been downloading exclusively from day one. I will buy them again and would highly recommend them to others in the aftermarket.
