Rollme has just launched the Hero, its latest smartwatch with a completely bezel-free display. This is joined by a nano-SIM card slot for 4G/LTE connectivity in this wearable, not to mention up to 4GB of RAM and 64GB of internal storage. Not only that, but it boasts an unusually large 1,600mAh battery rated for up to 10 days on power-save mode.
