Great idea to track actual sleep time and quality

Surprised at how well it tracks sleep time vs awake time vs restless time during the night. Mine lasts about a week between charges right now (about 3 months since purchase at time of review). Easy to setup and link to app on laptop or phone. Helps motivate me with the hourly reminder move especially when sitting in front of the computer at work or home. Watch for sale and it's a great tool to help with fitness goals. Not bulky, easy to forget I'm wearing it.
