Yes, it also "appears" to be just an empty shiny container with some wires and a blinky light. When you buy one, crack it open, and reverse engineer it, be sure to let us know what it actually is
and what its logic is.
That said, I'll wait until the incredible price gouging subsides to the point where this product is available for a reasonable price with reasonable profits still plentiful for TurboXS and distributors.
