i have various travel mugs, cheap and expensive, original Timolino I got fr Davids Tea, but i find I use this particular one daily. The main reason is slide-tab closure. i dont have to open it in order to drink. its especially useful in a car. It doesn’t retain flavors fr previous teas, i try not to forget and clean it every time. My cheap mugs tend to smell no matter what. i use baking soda or Efferdent, but they still smell.
