The bottle unscrew itself when I was pumping and dropped to floor and I wasted 4 oz of milk! All on floor! Smell so good but on the floor!!! I am soooo angry and upset!!!! ! I have already kept screwing it back but I don\'t know why it keep unscrewing !!! It\'s such a bad design even though it pumps well!!!
If you are using the small bottle, don\'t forget to put the ring on or else it will fall off easily from the pump. Otherwise, it\'s ok. I use the brown bottle (which doesn\'t come with the pump) and it does get loose. So I think it\'s better to pump with the white bottles and with rings on.
Let me write a formal complain letter and attach a print out of this forum and see what they say. This is too unacceptable!!! I pump more milk with Avent pumps! Medea pump somehow gives me less milk but if waste every few days I might as well use medala !!!!
I hate Avent too! Its design is bad! The loosely bottle will make you very nervous when pumping milk as you afraid the bottle may fall down any time. Moreover, there are too many parts and pieces, that complicates the cleaning and sterilizing process. It takes 20 min to pump but and more than triple times to unplug, wash, sterilize, re-assemble the setting! Horrible!
