Just wanted to share my experience with these Nenesupply pump parts after using them for 3 months with my Medela Pump in Style (2018 model).

The Good:
- Seriously, the price difference from original Medela parts is insane for nearly identical performance
- Love that everything is separable - makes cleaning SO much easier than one-piece designs
- The 24mm flanges work perfectly for me (I'm usually between 21-24mm sizes)
- All components feel sturdy and have held up well to daily use and dishwasher cycles

The Okay:
- The tubing is slightly stiffer than Medela's original tubing, but still works fine
- Had to double check compatibility before ordering since my pump is older

Pro Tip:
If you have elastic nipples like me, the longer flange design really helps! I do wish they offered oval-shaped flanges though - would make longer sessions more comfortable.

Final Verdict: 4.5/5 ⭐
For the price, these are an absolute steal if you need replacement parts. Just make sure to measure your nipple size properly before ordering!
