had the product been recommended by another mummy - and do not want to miss it - great product for milchfläschen make - simply water into the vial and into the warmer and thanks to the thermometer I know when the water has the optimum temperature - no tinkering constant, cold water to pour, etc. super !!!!! not unbreakable - but that's the way with all thermometers that have no digital display (so one I have tried, but I can not convince them, I 'swear to the Easy 1010 - Therm Baby Bottle Thermometer with Blue Star! !!!
