Misfit Ray Fitness Monitor
With a sleek, tube-like body, the Misfit Ray Fitness Monitor looks more like a piece of jewelry than a gadget. And that's fully intentional. Meant to be worn at all times, it's powered by replaceable button batteries, is water-resistant to 50 meters, has a multicolor LED display for quick progress updates, and a vibration motor for notifications. It'll track your steps, calories, distance traveled, and sleep, with the ability to label a slew of different activities in the companion app. It uses a spring bar system for connecting accessories, and its anodized aluminum body is available in carbon black or rose gold, with your choice of TPU or leather bands.
