It keeps my coffee or tea at a nice temperature (not too hot or cold) for as long as I have it on.

Makes an incredible gift and definitely keeps its warmth to make my coffee the perfect temperature.

But with this device, I’m able to enjoy the cup of tea at the right warm temperature each time & each sip

I had a business meeting with my boss where we had to leave our office for the entire day, and when I came back, my coffee was still at the perfect temperature

This works very well, and I like the temperature it keeps my coffee.
