Maymom all the way.
I’ve purchased multiple products from Maymom now, and all have been amazing.They work with my speCTra s2 breast pump and all the parts are great quality, they don’t cloud up either and I use the dishwasher to disinfect them.
Compatible with spectra s1
Parts are compatible and work great with the chargeable Spectra S1.
Nice length on tubbing
Bought this after my cate chewed up my other rubber tube. I didn’t think I’d need the extra flange parts, but they have been very handy.
Excellent match for the Spectra S1
Excellent art of replament parts for the spectra S1! Everything fits perfectly and it’s nice to know that replacement parts are easy to be found on Amazon in Canada. The tubes are longer than the standard set which is super handy, I’m able to put my pump on the floor and sit in a regular chair comfortably and have access slack available. Detailed instructions are included which was appreciated and a little storage box for extra parts too.
Great replacement kit
Got this for my spectra pump which you can only buy the pump in the states but everything fit perfect for my spectra!
Saved my pump
Decided to save some money and try these parts instead of paying 4x the price for the name brand ones. I see no difference in efficiency of these and would recommend trying then before spending too much.
Improved my pump output
I hadn’t changed my pump parts in a few months and finally did. The suction was way more and I got slightly more pumped! I wish I’d changed sooner
Works well
Got this to replace my spectra pumping parts. I love that the tubing is longer than the original ones making it easier to pump a little further away. I found the backflow preventer doesnât quite fit nicely into the original flange⦠you really have to force it in. Overall, good replacement set. Would recommend.
These are great replacement parts for my Spectra! I like that the tubing is a bit longer than what came with my pump, and the duckbills are more sturdy and less slippery than the Spectra brand.
I use these replacement parts with my spectra
Good quality. Works as it should with my Spectra S1.
Good replacement parts
I have the Spectra S1 plus and these pump parts fit perfectly, and work great. I honestly didnât realize it would come with extra duck valves too which was awesome because they tend to wear out quickly for exclusive pumpers. Definitely will order again being that you should replace pump parts every six weeks!
