Thermometers not suitable for drinking

Sorry to the seller, but unfortunately it was not possible to have a drink from the sealed drinking cup on the drinking spout to drink. the margin is extremely high and there is only one drinking spout. Therefore, no air can flow into the container, and it is necessary to suck virtually at the opening. But this also is not because the edge of the drinking cup is extremely high. the warming properties I have not tested. The mug is beautiful in itself and fits comfortably in your hand. Seems to be stable. But since I can not drink out of it - not advise unless as a flower vase. Have returned the cup.
