For my customer visits I often travel with various delicacies. It is important that the food has a certain temperature even after hours of transport. Recently I wanted to bring a fresh Nidelkuchen to a customer meeting. This is a Swiss one-day speciality for which cool storage is particularly important, otherwise the cake will melt. I was driving with the QOOL Box from Bernese Seeland to Lake Geneva. Once there, the Nidelkuchen was perfectly cooled and in shape.
