Willow Sync Diaphragm Set (2-pack)

The 90-day replacement reminder in the pamphlet is actually helpful—I set a calendar alert and it’s nice knowing exactly when to swap these out. I’ve been using the first diaphragm daily for about a month and the fit still feels snug with no leaks, so the second one is a smart backup to have on hand

Replacing these at the 90-day mark keeps the pump running smoothly, and the fit is identical to the originals so no guessing game. I notice the difference in suction immediately after swapping in a fresh set.

Three months in and these diaphragms still feel as snug and responsive as day one, which is exactly why I set a reminder to swap them every 90 days. The 2-pack means I always have a spare ready when the first one starts showing wear.
