I’ve only ever used spectra and cannot recommend them enough tbh. I’ve brought two - the s2 & s2+ across three babies
Spectra 2
Baby Buddha. It is INTENSE so not for the faint of heart but will get more out of you than any other pump in less time. Was important to me because I didn’t make enough for both and this helped. Not sure if it delivers in the UK
Momcozy defo the best out there but pricey so would reccomend looking on good housekeeping for reviews xxxx
