I love my Haakaa. It’s an excellent product for any mama who leaks a ton while breastfeeding. And great for saving additional milk.Possible user errors: As long as you suction it successfully and keep your babies’ feet away while feeding (mine enjoys kicking it, which results in spills 20% of the time; I’ve learned to “catch it” as she kicks �), and BUY THE LID (though they should include it) and properly put the lid ON, you’ll be golden (I can’t tell you how many times I’ve knocked it with my elbow on the table next to me). It takes some thought to remember all this, but has gotten easier with my now 4-month old. I am much happier with my Haakaa instead of leaking 4oz onto me and my baby, too. �
