Medela swing or Momcozy M5/ S12?

[OB51]

Hello,

I am currently pregnant with my first baby and am looking to buy a breast pump to suit my brestfeeding plans. I plan to breastfeed whilst also expressing so my partner can share the load but unsure of what breast pump to buy? I have heard mixed reviews about the pumps mentioned. Is it best to buy for 1 breast or 2? I have large boobs so ideally something that will suit that. Has anyone has any experience of doing this and can reccomend a pump or have used the ones I have mentioned? Feel like I have no clue on what im doing😔

Amazon have thier sale on so ideally would like to decide today!

Thanks!
