It is perfect in every way except that it could be a tiny bit thinner. I found the thickness of the plastic made the cup suck too hard and it hurt. I had to only lightly compress it and get little bits of milk and then lightly compress again so it wouldn't suck too hard.
I couldn't think of anything to stop wasting all the breast milk, I tried using ziplock bags in my bra which is a little funny and was making such a mess until then I came across the page that milk saver that actually exist! Money well spent, save milk means happy baby!

Love it! Money well spent to save liquid gold that would of just been wasted
I love the Mumasil! It has saved so much of my breast milk from going to waste! I am already planning to buy my pregnant friends a Mumasil
