I have been using the Chantal travel mug for 6 months. The attribute that set it apart is that you can drink the liquid anywhere around the rim. Most, if not all, travel mugs have a single exit for the liquid. It is dishwasher safe, easy to disassemble and keeps the liquid at a consistent temperature for a long time.
