Maymom Pump Parts Compatible With Spectra S2 Spectra S1, Incl Flanges (24mm) Valves Tubes Bottles Backflow Protectors, Not Original Spectra S2 Accessories Replace Spectra Flange Spectra Duckbill Valve

Funciona bien.

Me encantó, cumple perfectamente con la función, las utilizo para extractor spectra s2 y no le piden absolutamente nada a las spectra, sin lugar a dudas son una excelente inversión.

They are just like my spectra parts. Also came with 4 duck valves which was a nice surprise. I love that I can have backup parts without paying full spectra price. Only issue with the flanges is where the backflow connects it’s always loose. I have 2 sets of maymom and both are like this. If my elbow accidently bumps the backflow it comes right out. I don’t have this issue with my original spectra flanges as it has a very tight fit so I don’t worry about losing the backflow and suction.

Update - after posting my review, they reached out and sent replacement parts. Upgraded a star for handling it like it originally should have been taken care of.Multiple issues with the parts, including leaky valves and diaphragms that won’t seal. Tried calling customer service and left multiple messages with no response. Would not recommend... if you have issues, you are out of luck.

These are a great lower-cost alternative to buying additional Spectra parts! I get just as much suction with my Maymom parts as I do with the parts that came with my Spectra pump. The only criticism I have with this product is that the printed measurements on the bottles have faded significantly over several months of washings, so it’s difficult to tell how much I’ve pumped until I recant the milk into another container. Otherwise they’re holding up great!
