I expected it to heat up faster. I had a similar product from another company that did a much better job

Nice for winter. It keeps your coffee warm in the car and you can also connect it to your computer at home or office by changing the cable with a smaller watt USB port, but better, because it keeps it warm and not boiling hot!

Very practical, the lid leaks a bit and doesn't keep the heat or cold on its own. When plugged in, it heats the liquid too much to the point of burning. For its price, I recommend it.

It keeps the drink warm for several hours. Just if you connect it to the car, it may burn it a little more. Otherwise, for its price, it is very good!
