I bought my spectra S1 on Amazon (the US site as Im in Canada) I also have M5s for when i’m on the go. Spectra was the game changer for me when getting my supply up and now I’m pumping 230-250 ml in 10 mins each pump.
Loved my Medela swing pump, lots selling on Vinted second hand, I found it was really useful and I couldn’t have done my pumping journey without it!
I use both the Spectra and the M5. I established supply with my Spectra first. After using both for a month, I can say that both drain my milk the same.
I got my spectra s2 on Amazon but you’d need a pumping bra for it. I have the momcozy v1 pro from Amazon that’s hospital grade and I find it empties me better than the m5s and spectra I love it
I have a spectra s2 and love it I brought it of Vinted for like £40 had less than 100 pumping hours recorded so it was relatively new and I just brought all new parts for it I also have the Elvie stride and also love that
