After using the Nenesupply pump parts for several months with my Medela Pump in Style, I can confidently say they deliver the same suction power as the original parts—but at a fraction of the cost. The 24mm flanges fit snugly (though if you're between sizes, consider sizing up), and the detachable design makes cleaning a breeze. No more awkward scrubbing—just pop them apart and toss them in the dishwasher.

What surprised me most was how quickly they dry! Unlike some sticky silicone parts I’ve used, these are ready to go within minutes after washing. The long flange length is a lifesaver for elastic nipples (no more constant readjustments mid-pump). My only nitpick? I wish the flange opening was slightly oval-shaped for extra comfort during longer sessions—but it’s a minor trade-off.

The tubing connects securely to my older Medela model (post-2006), and the valves haven’t lost suction even after months of daily use. Pro tip: These work brilliantly with hands-free bras since the flanges detach easily from the connectors. For anyone tired of overpriced OEM parts, this set is a no-brainer—just double-check sizing if you’re sensitive to tighter fits.
