Super versatile
These are great flange inserts. I have used them in my Spectra S2 standard 24mm flanges, the ones for my Eufy S1 Pro wearable, and my Medela manual pump – they are perfect in all three! Love that it allows me to use the standard included flanges and get a much better fit – far better comfort and output.

Too big for Eufy but works
A little too big for the Eufy S1. Motor does not seal completely against the collection cups. It still works though!

POOR QUALITY CONTROL
Literally none of the 12 duckbills I was sent were cut properly so the opening didn’t close at all for proper suctioning and preventing backflow. They’re weirdly lopsided. Will be trying to return if I can. Don’t waste your money, poor quality control! Will worsen pumping efficiency!
