Habervision no-fog
I received mine a few days ago. They claim the battery life is "estimated at 15 hours". Installation was easy enough in my scott goggles. They don't seem to obstruct vision much, maybe the top 10% of the lense. There is an auto setting where it senses humidity and turns on to vent it out. Can't feel any air flow across my eyes. There is a little outside of the goggle coming from the foam above the unit. Just waiting for snow to see if they work.
