So much easier
So easy to use compared to standard pump set up. I bought as I returned to work to replace standard spectra pump flanges etc works really well with the S2 and had made fitting pumping into my work day so much easier than dealing with pumping bras and extra bottles. Also just feels less mechanical! The volume is great and U was able to reuse the spectra flange adapter's (17 and 19mm) that I already had.
