The Basis B1 Band is a stylish, watch-like tracking device that should make die-hard fitness fans happy. The B1 Band has a retro look to it that PC Mag calls "casual and straightforward," but they still had some issues with the overall design, like that the "backlighting is horrifically dim." Knowing that users would be wearing the device on their wrist all the time, Basis made the B1 Band water resistant, but Popular Science says they "wouldn't go deep-sea diving" though they were able to wear it everyday in the shower with "no problems." On the backside of the device are sensors to measure your blood pressure, steps, intensity, and exertion of your workout, and sleep metrics which allows you to tie them into what Basis calls "Habits." Habits are what Basis uses for motivation, awarding you points for things as simple as wearing the device, not sitting, and even going to bed. TechCrunch says the use of Habits "encourages you to visit the website often and unlock new rewards," but "rewards are so open-ended it's difficult to remember some of them" and the B1 Band "won't remind you." The Basis B1 Band is one of the most comprehensive trackers out there, but it's also the most expensive at $199. At just $99 both the FitBit One and Withings Pulse offer better value for the money, but if you're in need of serious metric tracking you'd be be wise to consider the Basis B1 Band.
