No thanks. If your gloves aren't working well enough for you then you can buy those hand warmer packets to put in your glove for a lot cheaper and without the battery pack hanging from the top tube. I accept winter riding for what it is and enjoy it, though some days are indeed tough to deal with especially with bitter cold headwinds. It's a challenge though and one which pays off well come the spring time when you'll have a head start on fitness than those who didn't ride.
