Does this skin protect the weakest link in the drone: Exposed not covered motors, if the water gets there, the drone might get damaged.
The skin increases weight and changes aerodynamic profile if anything it might handicap the drone in extreme conditions. Since battery lasts less in extreme conditions eg 20min handicapping it by a minute as you suggested equals to 5% battery performance decrease. Also makes it totally illegal in Canada without pilot licence.
Let's call it what it is: colourful Mavic Mini skin for a drone, tradeoff to look cool 5% of battery time, and it should be everyone's individual decisions if they are ready for the trade-off or not.
There is huge market for all kinds of skins for phones, watches, cars, camera, ipads etc.
Why adding all other claims that seem so hard if not impossible to prove, also people might lose their bird if they decide to fly in “extreme conditions” thinking this wet suit will protect them.
btw I flew MM in light rain, snow, -4C and 50km/h wind, over the reflective water without a skin, battery was doing fine, sensors were doing fine as well.

I really like nee colour skin idea it makes young generation happy, and thats fine, but lets face it above wet suite will not turn MM in to rescue drone.
