Smart watches and smart glasses have been all of the rave as of late, but slowly sneaking into the world of wearable devices is stuff like the Smarty Ring. With the name pretty much saying it all, this styling piece of tech will never let you go without missing a notification. With Bluetooth 4.0 you’ll receive text and email alerts, incoming call and outgoing call notifications, along with real time updates from social networks like Facebook, Twitter and Skype. The stainless steel ring can also be used as a watch, timer or phone finder and lasts up to 24-hours on a single charge.
