After using the Nenesupply pump parts for 6 months with my Medela Pump in Style, I can confidently say they deliver the same suction as original parts—but at a fraction of the cost. The detachable 24mm flanges were a game-changer for my elastic nipples (no more awkward tugging!), though I agree with another reviewer that an oval shape might’ve been even comfier.

Cleaning is a breeze thanks to the separable design—no more scrubbing hard-to-reach crevices. They dry lightning-fast, which is clutch when you’re juggling pump sessions between meetings. Pro tip: The tubing’s dual-end design (one stiff connector + one soft end) made it super easy to snap into my pumping bra hands-free.

One heads-up: If you’re between sizes or have fuller breasts, consider sizing up from 24mm. While they worked perfectly for my 34B frame, the fit felt snug during longer sessions. Still, for under $20, getting TWO complete sets (flanges + connectors + valves) makes this an unbeatable backup kit for moms who pump frequently.
