I'm reasonably sure you have a freezer compartment is your refrigerator. I suggest you pull the eyepiece and put it in there for 30 minutes or so and find out....
I know you can do that. The new one I tested was NIB, I borrowed if from a friend who happens to own a gunshop.
The older model belongs to a fellow hunter. No issue with that one.
NIB but inoperable at below freezing temps is no good, least in my view.
There is quite a lengthy thread on this site concerning that issue, you might want to do a search for it.
Not trying to rain on your parade or be a smartarse, just alerting you that an issue exists.
