Replacing my trusty thermos mug

Time to replace one vacuum cup with another. The plastic cup on the left was supposed to be unbreakable and well it hasn't. Nevertheless it looks worn. I think I have had it from 2005/6. It doesn't work as well now. You can tell from the condensation on the outside each time I pour a cold drink into it.

I have tested the new one ($21 after discount at John Little) for both hot and cold drinks. It is working well.
