I was skeptical about needing replacements this often, but the seal on these duckbills feels genuinely tighter than my last set, and I noticed the pump pulling more consistently right away. The 90-day mark is easy to track since I just write the date on the bag with a marker and swap them out.
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.
