Ann: Wave II LIcensing Term Sheet Executed, page-22

I'm even thinking that that is an early Photoshop... If it were a real device then wouldn't the larger end cause it to fall off that hand model's thumb? Her index finger is on the wrong side of the pivot point to prevent it falling off her thumb (if you know what I mean).

Also, the perspective at the applicator face seems to be skewed...

(My opinion anyway)

Regardless, the photo of the Adelaide presentation seems to be a more realistic device, if it is to incorporate a battery.
