eufy 雙層密封喇叭罩（27 mm）適用於吸乳器 S2 / S2 Pro

The double seal actually makes a difference — no more leaking when I lean forward while pumping. Snapped right onto my S2 Pro without any wiggle, and cleanup is the same as before.

I was skeptical about the 27 mm size, but the double seal holds it perfectly in place with no shifts or leaks during my whole pumping session.

The double seal actually makes a difference — I'm getting a much better suction than with the original flange, and no milk leaking around the edges anymore. Popped right onto my S2 with no wiggle.
