To celebrate the launch of the Fitbit Ionic, built with their most accurate heart-rate monitor ever, we created the most heart-racing unboxing video ever.

‘Ultimate Unboxing’ was shot in Barcelona, and stars unboxing expert and YouTube superstar SuperSaf. The film shows SuperSaf put the Ionic’s heart-rate monitor to the ultimate test, by reviewing the smartwatch as he skydives from 14,000 feet.
