Live smarter with the black Razer Nabu X Smartband. This activity tracking wristband keeps tabs on the steps you walk, the distance you travel, the calories you burn, and the hours you sleep to give you the information you need about your physical activity. This information is sent back to your Android or iOS device over Bluetooth, where you can view, track, and compare your data with other Nabu and Nabu X users.
Three LEDs along the top of the band and a vibration motor alert you to mobile notifications. You can set what colors the indicators flash in when you get incoming calls, alarms, or notifications as well as customize the intensity of the motor's vibration. If you set an activity goal in the Nabu X's free companion app, you can also double tap the top of the band to view your progress.
Your Nabu X is outfitted with Razer's Pulse technology, which lets you exchange social media contact information with another Nabu or Nabu X wearer by high-fiving. You can also compare your activity and play multiplayer games with other users when nearby.
The lithium-polymer battery in the Nabu X lasts for 5-7 days depending on use and the device is splashproof, so you can shower and wash your hands without fear of damage. Its detachable one-size-fits-most strap accommodates wrists 5.3 to 8.3" around, and it includes a USB charging cable.
