    This is the perfect gift for a real coffee drinker. My mom loves to watch the morning news. While watching she often has to stick her coffee cup in the microwave. Now she can pour a big cup because i got the 14oz and enjoy it without having to get up to microwave it. Her coffee stays just like when she first poured it.

    This mug does a good job of keeping your beverage warm, however don’t expect it to do so for long. If you like your beverage hot, it will only keep it that way for approximately 30 min. You could extend this by keeping it on the charger while your not drinking out of it.
