The Mobius Maxi has a known flaw, plus at $70.00 it isn't particularly expensive. Then again, the original Mobius 1, also sells for $70.00 is one of the most reliable dash cams ever built. Either way, comparing an otherwise highly reliable and well built Mobius Maxi, where
some people reported bricking their cameras during firmware updates with a $10 generic rear view mirror camera that could fail unexpectedly at any moment is an apples to oranges equation which makes no sense. Then again we know you are fond of touting your redneck logic.
Obviously, any camera can fail but the fact is that most knowledgeable and experienced dash cam users go out of their way to install the most reliable camera set-up they can. They don't stick a $10 rear view nirror camera on their windshield while keeping their fingers crossed.
