Freestyle offers a completely mobile solution with its integrated, rechargeable battery with up to 3 hrs of pumping per charge. You'll love the freedom to pump anywhere, anytime with maximum efficiency. Pump hands free when paired with a breast pump bra (I have a well loved size small one that I am happy to throw in if you like). I did so much research before I settled on this pump. With all the extras this was well over $500. Well cared for and sterilized after each use. I tried a few pumps and was a milk donor for the hospital. The freestyle was my favourite by far - so simple and works great. Throwing in a bunch of extra medela bottles (16 total - 10 standard sized and 6 large ones) all compatible with pump and freezer safe - several never opened still in packaging. Also throwing in a medela harmony manual breast pump. Including 3 almost full packages of Lansinoh breastmilk storage bags. The one I ordered did not come with the cooler bag but includes all the other parts and all the above extras! Also happy to throw in the size small medela pump bra in additional photos if it will work for you 😊
