At first I did classical sterilized in a pressure cooker that was me at some point, however, too expensive and dangerous, because when the baby is crying and you go from the stove, there is ever a risk that you have cooked Schnullerbrei. After I took a microwave bag, with whom I was very happy, because you throw all things only in the bag, water had to give, and then into the microwave. These bags can be used, however, limited and five pieces are quite expensive, but not last forever. Since I find the device by Chicco better. You have to clean and going even do everything in the appliance, water. It is of course very hot, shortly after the end, but if you can just stand first, everything is clean and dry, especially. Class is that insane reinpasst much. I really have sterilized every nipples, soothers, each bottle and all covers in 2 passages. And if you do not open the lid, everything stays up to 24 clean - it really is my favorite and I have so well yet seen anywhere else. The price therefore the best investment ever!
