The sizing on this replacement insert is spot-on, so my pump stays comfortable even during longer sessions. It clicks in securely and feels just as snug as the original. Glad I grabbed a spare so I’m never stuck with a worn-out fit mid-week.

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.
