We have the "vaporizer" for four weeks in daily use. Compared to the boiling of bottles and teats in a pot he has a large gain in comfort. The device is quite large; that is, it offers plenty of space for the material to be sterilized, but also takes a correspondingly large space. The design is surprisingly rickety: The plastic is not very rigid, the use to which the vials are held, is not neat and sometimes does not even the top cover completely. For this price I would have expected a more solid quality. Annoying Details: The measuring cup for the hot plate to be filled water is not about the size of the necessary amount of water, but even half must be filled completely and then again for good. After all, there is a scale. A switch does not exist; if one or similar when cleaning accidentally pressed the power switch, what happens easily, you have to pull the plug so that the unit does not start to heat up. But you can live with. Overall, the unit what it is doing, and has made everyday life with suckers and vials lot easier. We no longer want to do without it, one would have expected for the price but a more solid and more elaborate version.
