Some info that may or may not apply. If you are storing the Spark and controller in a cold dry invironment and then take it to a warm moist invironment it most definitely will cause condensation. This could affect the lens as well as the joy sticks. Hope this helps.
I have had care refresh and then care refresh+. I inadvertently let the care+ expire 2 days ago and now they won't renew it, or maybe they will only do care refresh for 2 years, I can't find out!
