I received it today (ordered there 3 days, very fast delivery). I followed the instructions (10 mins to load, then unplugged) for more than 2 hours and it keeps me warm and replaces my traditional water bottle. I find this product for what I needed (not too big to have it with me even in the car or when traveling during the winter and no need to worry if I fall asleep at night with- not need In this case reconnect for hours). For now it matches the description on amazon. We will see the life, I will use a lot this winter, but right now (first time) I recommend. Thank you.
