Don, just got off the phone with Gerbing customer service. What a fantastic company, they could not be nicer. I told her my problem with the gloves at below 35 degrees and told her my Gerbing Jacket had the opposite problem, it cooked me until I got a duel controller where I was able to control the gloves and jacket separately. She told me to send the gloves in with a note, they would check them and if not perfect they would replace them. If they checked out OK, they would go ahead and add more heating element to them (no charge for this) and return them. I told her I was not sure if they were still in warranty and she said "if they are Gerbing, they are always covered under our warranty". I'll send mine in today and post it when I know something.
