I'm betting it was like the kid who stuck his tongue to the pole in A Christmas Story.I used my gear on Denali in near -40F temps. Just had to watch for condensation when going into the "warmth" (-20F or so) of our tents. Batteries can be problematic - needed lots of them. You just have to take care.
Edit - One other thing to take care of in deep cold - no metal on bare skin! I made the most God-awful mistake of putting a carabiner in my mouth in those temps. The result was "most unpleasant".
