Hi can mummies who are using Spectra breastpumps give their reviews on the various models? I wanna buy one but I don't know which model to get.

For spectra, i have S1, 9S and M1 . S1 have a better yield , hospital grade . 9S is batt or cable operated . they have a 9+ as well . works the same. i finds it too gentle for me and very often not able to empty . M1 i dont like it even it have a high rave for it . reason is i also cant seems to empty it too . and the batt span is only for 3x30mins cycle. If u are an over supplied mummy, s1 suits u more. but its bulky and weighs more than 1kg. I drive, so its not an issue for me. Otherwise, i would prefer 9S than m1
