This smartwatch doubles as a wearable wireless storage. I'm sorry;but, I don't get the point of the ReVault smartwatch. Its main feature is that it can store up to 128Gigs of data. Ok, but why not just carry around a micro USB card or a standard USB stick? Who needs wireless local storage on your wrist? My Galaxy Note 4 phone has a 128 Gig micro SD inside, and it stores just about everything I would ever need. It does convert into a keychain or a necklace; but, again, just get a USB stick and put it in your pocket, phone or briefcase.
