The flange insert clicks in and out of my pump so easily that swapping sizes between sessions takes seconds now. It holds its shape perfectly after multiple washes, and having a spare on hand means I’m never stuck fumbling with a loose fit mid-day.

I was worried the fit might be off, but this single insert snaps right into my pump and holds securely. The silicone is soft enough to be comfortable during long sessions.

Finally found a replacement for the one I lost, and it fits perfectly with my existing pump. The silicone is soft and seals well, making it comfortable for longer sessions.
