The soft, flexible edges really do make a difference—no more digging into my skin during those middle-of-the-night sessions. Fit is snug and secure with my Signature Pro, and milk flow seems steadier than with the harder plastic ones. Genuinely glad I switched.

Hazel T. ★★★★★ Aug 28, 2026

I was skeptical about replacing my old flanges, but these fit the pump so snugly that I actually get a better seal without having to press down. The flexible edges mean no more red marks on my skin, and pumping feels noticeably more comfortable.

The sizing is spot-on for the Signature Pro, and the flexible rim means no more red marks after a 20-minute session. I’ve tried cheaper plastic ones before, but these actually seal properly without pinching, which has made a noticeable difference in my output.
