There are many people want to know the pro and cons of Medela Freestyle vs Avent ISIS iQ Duo since both are well known double pump electric. Here are some explanation:
Features common to both: Both pumps are adjustable in strength and frequency of pumping action, and both can be customized with soft breastshields (these come standard with the Avent IQ). Both are now BPA-free. Both can also be used as a single pump if you want to, for example, pump one side while your baby feeds on the other. Both come with a carry bag, basic bottles, cold bags and cool packs. Both are compact, and look reasonably presentable (the Avent more so), if you forget to tuck it into a desk drawer before a meeting.
