It's an order of magnitude more convenient than using a microwave to heat water. Although the capacity is not quite that of a kettle, it's great for single servings.
Positive Product Points
Heats 16 oz of water to a boil in less than 90 seconds. Smaller footprint than a kettle, cheaper than an electric kettle, small enough to stash in your office. Automatically turns off right at boil.
Negative Product Points
Not quite tall enough to fit even a 3 tass (12 oz) press under but that can be worked around.
Detailed Commentary
I have this unit sitting in the break room at the office where there's about six of us who use it daily; to make tea, instant coffee (shudder), ramen noodles, easy-mac, etc. It's a lot more convenient than using the microwave to heat water as it takes a little longer and the water can get superheated. I myself use it for tea and for the french press. Unfortunately it's not tall enough for my 3 tass press to fit under so what I do use use a mug to brew in then transfer in to the press to press out the coffee. If it were not even 1/2" taller it would be perfect for the press.
