A Wearable That Controls Your Body Temperature? : The Embr Wave

We are in the future ladies and gentlemen! But this is Pricey! ....$299 (would you buy this?)

The Embr Wave, a heating and cooling bracelet, is designed to make you feel five degrees hotter or colder in just a few minutes. It's now selling at Urban Outfitters and I can't decided whether or not it's worth it. You be the judge.
