Love it!

Fits exactly with my spectra pump, flanges fit well, and loved how everything was individually packaged! Arrived quickly too!

Everything fit my Spectra perfectly and the 19 mm flanges are great - just a little bit smaller than my 20mm from Spectra, but makes a big difference. The tubes are longer which is convenient.

Excellent set of replacement parts for Spectra. Maymom is also compatible with Medela, so they've made a rubber bottle ring to create good seal between flange and bottle no matter which pump you are using.
