The device can make you feel a bit better but it can NOT replace an AC.

It was never designed to replace an AC.

If this was up for purchase i would get one especialy because it is portable and maybe it can be coupled with additional technology (measure blood preasure , acceleration, rfid access tags,...). People have been wearing wrist bands for ages (and even used them as currency) so it seems a good position for a gadget.
