Agreed, it seems bizarre that they're so cagey about the capabilities. Even companies that release product datasheets under NDA offer key specifications in a product brief.

Well that was impressive, :horse:
The LEDs were a bit dim, I can see super bright LEDs lit at about 1uA, 50Hz leakage through my fingers is enough to light them.
Their TX doesn't have a power on LED to solve the "not been plugged in problem" ?

At least we know he's not pressing a secret button on the receiver to activate the LEDs.
(unless it's a double-bluff :popcorn: )
Questions:
a) Why would it take 30 seconds to warm up?
b) The receiver is huge, why does nobody notice that it's going to need a humongous phone to work and that the space would be better used by simply adding a bigger battery instead of this garbage.
