For us it is crucial that these cups have a good grip cover and without cover a prima basic stiffness in the cup. Prima handling!
Here, then, our personal line-up: Breast Pump Lansinoh, Microwave Steam Sterilizer Avent (who really little difference), storage cup of MAM (good strength, grip cap) and the teat and bottle of MAM (here absolutely convincing the anti-colic bottle; can even be detached sterilized in microwave).
Hope that helps ...
