Customers say
Customers find these breast pump parts work perfectly with Spectra pumps and consider them better than original Spectra parts, with good value for money. They fit Spectra pumps well, particularly the Avent bottle lids, and customers love them as replacement parts. The plastic durability receives mixed reviews, with several customers reporting parts breaking within 15 uses. Leakage and suction performance also show mixed results, with some customers reporting good seals while others experience milk leakage and issues with suction.
