This brand has almost no need to advertise as its products meet consensus with parents, and I will not deviate from the general opinion. The product is perfect! At the birth of my daughter I had first bought the competing brand Advent, but when colic began, I looked that existed to address them and came across this brand. I could not believe too good but I tested by acquired conscience and finally it really helps! And especially when I had purchased for the anti-colic system 160ml, I noticed that my daughter was taking much better in the mouth these teats and thus she already swallowed less air. Their platform is really perfect (not because it mimics the breast to me, but also because it adapts to the natural shape of the mouth that is not O when drinking!) Finally when my daughter grew up, I naturally bought the size of the bottle 2 and debit teats 2. They are really good and for trying them and Advent with thickened milk, and I have never had a problem nipple clogged with Mam, whereas with Advent 3 or 4 times, so I strongly advise and make and model for the thickened milk (or when baby grows!).
