Great Pump Parts Set
This is a great and affordable pump parts set. According to my measurements, I needed a 24 mm flange set, but when they came, they were way too big. This is probably a measurement mistake on my end, but I would recommend being sure of your flange size before ordering a whole set since they canât be returned once youâve used them. I ended up buying just the flanges separately in a smaller size. But if youâre confident of your size, this is a great set to buy and is compatible with the Spectra S1 and S2 pumps.
Perfect fit for Spectra S1
This set of pump parts is great. I wish it came with bottle nipples but other than that Iâm very happy with it.
Amazing customer service, don’t hesitate just buy it!
Maymom has outstanding customer service! The flange I ordered didn’t fit me properly & they were very responsive, very generous & so helpful in getting the right product into my hands. The flange was too short for me, & they didn’t just say sorry about your luck, they provided me other alternatives until we found one that worked…they even sent me a prototype of a new model! So happy with maymom!
I wish I could love them
I love these parts and they work great BUT.Iâm not going to have to get a third set because once again the backflow protectors have broken off into the flange.Not from pulling on them, quite literally just from them falling over on the counter and snapping off into the flange.
Good value. Would buy again.
These after market parts work perfectly with my spectra pump. Very happy with this purchase. I would buy again. Shipping was fast.
Works great with Spectra S2
These work great with my spectra S2 pump. I didn’t want to buy a whole new pump but my original parts were starting to look really rough and I wanted a new set for baby number two. This was a great purchase.
Terrible quality – very disappointing
The overflow for milk spillage was broken and so only one of the pump parts are useable. Very disappointing given price of item and also fact you cannot return a broken item – would not recommend these spare parts for the spectra pump at all.
The parts from Maymom are almost identical to my Spectra parts. The differences Iâve noticed are:-The valves in the Maymom kit are stiffer than the Spectra valves, which makes them more difficult to remove from the flange.-The Maymom flange is made of a very slightly thicker plastic and the outer rim of the flange appears just barely smaller in circumference than that of my Spectra flange. (Both 24mm flanges.)-The bottles that come with the Maymom kit are more ergonomic as they have indents in the sides to make them easier to hold, plus they are shorter, so I tend to hit the bottom of the bottles on things less as Iâm pumping.Personally, I feel that the Spectra flange is a little more comfortable. I seem to yield just a bit less milk with the Maymom pump, it seems, having used both brands for a couple days, but itâs such a small amount of difference that it could be dependent upon other factors (diet, hydration, etc.)Overall, itâs definitely worth the purchase for nearly half the price of the name brand set.
