Okay, so I was skeptical at first because let's be real - not all replacement parts are created equal. But these? Total lifesaver.

First off, they fit my Lansinoh pump PERFECTLY. Like, zero difference from the original parts. I've used them for weeks now and no leaks (unlike some other reviews mentioned - maybe they got a bad batch?).

The duckbill valves are clutch - milk flows one way like it should and the suction feels just right. Plus the silicone is super soft which matters when you're pumping multiple times a day.

Major bonus: They include different flange sizes! As someone who doesn't fit standard sizes, this was huge. The 24mm works great for me but having options is amazing.

Cleaning is stupid easy too - fewer parts to deal with than my old setup. Just toss everything in soapy water and boom, done.

Only thing I'd say is measure your nipple size before ordering because flange fit is everything for comfort and output. But if you get the right size? 10/10 would recommend.

Already bought a second set because washing pump parts is the actual worst and having backups saves my sanity.
