The order arrived earlier than expected. It was nicely packed and well protected. I was so excited and used it immediately after it has arrived (using direct power supply and 5V / 2A USB plug as recommended). Unfortunately I was very disappointed as it was not warm enough for my cold feet. I folded it into half and put my feet in it. I also put it in between two rugs/mat hoping to increase the heat retention. I even left it on for about an hour while I did my housework around my house hoping it will be warmer but the result was still disappointing.
