Aihhh Cimirle F1 tu memang lembut, kak! A few of us tried it and honestly suction dia not too strong which is good for sensitive nipples, aku rasa brand macam Spectra S1 atau Medela Freestyle Flex pun okay jugak, but kalau you specifically cari yang sama gentle macam F1, the Cimilre ones memang paling recommend dalam our mum group lah. Maybe try the Cimilre models lagi since you dah tahu yang suctionnya suits you?
