Willow Sync ダックビルバルブセット（2個入り）

These are the exact same shape as the originals that came with my pump, so the seal is perfect and no more leaks. I appreciate that the pack gives me a spare, and the 90-day replacement reminder is actually useful since I always forget.

I’ve been swapping these out every few months and the fit is just as snug as the originals—no leaks, no fuss. The 2-pack means I’m never caught without a spare when I need it most. Honestly, it’s a relief to find replacements that feel this consistent.

The flow is noticeably better with these valves—my pump works more efficiently and I’m actually getting a few extra ounces per session. The seal is snug and doesn’t leak, even after a couple weeks of daily use.
