You being impressed is not the point of this product or this thread.
Its like the second someone comes to us and says “hey, Ive got a solution for you to recover your drone from a body of water for DJI Care Refresh”, and “actually get your sd footage back too, no wasted work”, and folks jump straight to “eff that, if it doesnt turn my drone into a submarine, it sucks”. Humans will never cease to amaze me.
