Here's a review for ya... Got back at the beginning of this month from a ski trip in Montana. First couple days, I kept taking my gloves off to access my phone unitil I remembered that my 920 has the super sensitive feature. Turned that puppy on an worked like a charm. It's not as responsive as using a bare hand, but it worked fine and was very useful during the week. My gloves? Hestra Army Leather Ascent. I'll let you decide if those qualify as "heavy duty" or not.
