I used the usb to heat the gloves. One gets a bit warmer, the other does not.The glove is not fit for women, it is far too wide at the wrist, even with the adjustable strap.
Right Side has problem. But Seller told they will send me another right side. I recommend the seller for their quick response. After receiving the right side again, I will test them and make a review video on this. Till now I can say good packaging and communication.
