I've used the single point heat-troller for 3 seasons with gloves/socks. Never had a problem with it. I do just use the on-off switch for the jacket and pants liner so I don’t notice anything going on with the battery. But then again, I don’t use the jacket or pants until it gets below around 20f. Battery is nearing 2 years old, but as of yesterday, things with the gloves and the ‘troller’ were still working just fine.
