At first I thought, oh so a warmer not need. The food is always freshly prepared. The part you can buy you if the little one starts with glass. But each of an infant has at home knows how loud the little mice can be if it is not super fast are the vial. Especially early at 4, it is really great. Boil water, through a small Abkühler leave (also a great acquisition) run (because the food can be cooked so only at about 40 ° C), powder pure, shake and bang the bean are already less than 5 minutes rum and the Small has roared awake himself. Then I've read some reviews because I was looking for a food warmer with warm function. And I must say, this is really great, and keeps completely what it promises. Meanwhile, I do it at night so that I've been preparing the water and put the food warmer to keep warm. If my little one then announces, I take the bottle out, pure milk powder, shake - ready. Takes not even a minute and the little one is blissful. Especially do not check if it has the correct serving temperature is. Because it's just right. Although the Little makes a brief water break (he is not the best eater), then simply reingestellt the finished bottle again and the temperature is kept super. Just when I'm traveling. Since I have the warmer here often. It is small and handy and fits in the diaper bag. A product which I can really recommend :)
