I’ve always purchased AC on my phones, iPads, MacBooks, etc. for peace of mind, totally worth it to me.
However - I’ve never had to use it in like, a decade? So you could get away with it. That being said, I bet the first device I skip will have some sort of issue…I’m in too deep.
I uninstalled Vibrant, didn’t have a need any longer. Looks great on the LCD!
