I had been looking for a reliable schn long, dense primarily Thermometers with free injection mechanism. Except for the coffee roaster was there not much to be found, although the selection of surfing is plentiful. At a sporting event, I arrived at the Contigobecher randomly. I am simply beheistert since the opening mechanism for drinking and pressure compensation funtioniert virtually splash-free. The content itself remains in use at least 2 - 3 hours drinking pleasant warm to hot. I actually had the stainless steel version first in genbrauch - the now my wife. Therefore, I now have the plastic cups, but with the same reliability and without the feared loss of taste or off-flavor. Cleaning can be both straightforward. The dishwasher letting outside before anyway, because that makes with plastic anyway not as good and the paint is not to suffer - is recommended by Hersteleer even so. Einzges shortcoming is de4r temperature loss over the cover; I given the other quality like negligible. Best product for me since the bottle !!!
