... When grilling and roasting a must ... We use it at present but rather to measure the baby bottles of milk;) Very useful! :) Update March 2015: The part is indestructible! Once done inadvertently with the dishwasher and washed. After drying again! Forget the meat in the oven: heat has the display can be black from the inside (display color ???). Thought because it's double trouble. Let stand 1 hour: Tadaa: Back again! So almost indestructible part!
