Mine live in my garage year round, I have a space heater for print days which has worked into into the -20c, lucky of I hit 5c ambient but enclosed printer helps. Have had no issues with the setup for years, it’s super dry in the winter so never had any issue with condensation, maybe a different story if I brought it in, but still idk if I’d be worried, you could use some dielectric grease if you’re really concerned but I personally think it’s overkill.

Cold enough things get brittle, but I wouldn’t be concerned for storage.

It could totally be setup to feel/work like a trackball, remember playing a bunch of warframe with mine and being able to “throw” it and have it stop when you touch the pad again, took getting used to but substantially more flexible than a regular analogue stick.
