It does keep my coffee or tea at my ideal temp. Battery alone doesn't last long, but when it on it's charging plate I've come back after going to the store and had it still at temp. Though the software has been flaky. Sometimes it does and sometimes it doesn't.
I could do the same with a hot plate and mug, but then I wouldn't have the pretty user interface on my phone to play with the temps. It even sends a notification to my phone when my coffee has reached my ideal temp if it was poured too hot or cold.
