Full compatibility: It can be used with the MAM Milk Storage Solution and the entire range of Easy Start bottles, allowing for breast milk storage or instant use.
Easy to use. Easy to learn how to disassemble and reassemble! Although at first that seems scary but it’s really easy and simple. Screws straight into the mam bottles. Causes no discomfort to the user and quiet enough so you could use at work or in private if you needed to pump quickly.
