The number 1 best-selling mug on Amazon doesn’t have a snarky expression on it, and it doesn’t say anything about the #1 dad or mom. Instead, it’s easily the greatest mug you’ll ever find.

This way you can ensure that your first sip and your last sip are always the exact temperature you like. You can even save different temperature settings for different beverages!
