I have bought myself the pacifier tree sterilizer because I silent and I need except the Schnullis nothing else boil. In the pressure cooker to sterilize Schnullis was totally awkward. With the pacifier tree that goes totally fast and uncomplicated. It can be sterilized in 6 Schnullis 90 seconds. In addition, the portion is pretty small and does not bring a lot of space. Would I buy again at any time !!!
