Wide Mouth Base Connector 2pc - Compatible with Motif & Spectra S1 S2 Pumps & Bottles; Compatible with Medela, Maymom, Pumpin Pals, Lacteck & Idaho Jones Flanges - Replacement Pump Parts Adapter

Leaky and did not fit any adapter flanges well. Makes air bubbles during pump. Update #1: Seller reached out to provide support for faulty product and were very accommodating in providing a replacement. Will update again once replacement is recieved and tested. Update #2: The replacement set sent to me works better than the first - no bubbles and leakage from the adapters. Would recommend this product, especially for the spectacular support for any malfunctioning products.

Used for lacteck flanges in my Luna motif. Does work but if it falls forward, it spills from the sides. Good for the price but be careful not to tip bottles over. Also hard to clean, gunk gets stuck you need to bend a bristle brush to get into the corners Edited comment: I rated this 3 stars but changed it to 5 stars because the excellent costumer service team refunded my purchase completely unsolicited. Obviously my review still stands true but the way the company handled it was very impressive.

EDIT: Because the last set I had purchased did not fit well, I was sent a replacement set, which fit flanges better than the previous set, though it was not a perfect fit, it made pumping with other flanges easier and more versatile because I can use different flanges for the Spectra instead of the standard ones, which does not work as well for me. ___________ Purchased this to use with Pumpin Pals Flanges as it was advertised to fit them, however, the connector itself is so tight and small that the flange hardly fits, and causes the flange to fall off from the connector while pumping. Super frustrated as I was excited to get these, and used it right away after sanitizing it.

My valves which are spectra brand sometimes slip off during the pump and fall into the bottle. The valves I was sent from Aeroflow seem to be too loose and fall off constantly- those are off brand. I also have issues with the bottle coming loose like it’s being unscrewed when I have it screwed on. Luckily have been able to catch that and screw it on tight again before spilling milks. I use these with the maymom lamp flanges and fit seems okay for that

These absolutely suck. I use 5oz bottles with these. Halfway full and it’s like it too heavy and they disconnect and fall. I’ve lost so much milk because of this. Milk spills from where you tighten it to the bottle even tho I make sure it’s super tight. Do not waste your money on these

These are great! And easy to clean. I like them more than the maymom ones

Works well to attach soft silicone flanges to spectra pump.

These were great to connect my spectra pump to my Pumpin Pals flanges. I will be ordering more so I can have a few sets. You will need to bring your own duck bill valves, they are not included.
