Comfortable band to wear. 3 sizes for little to big fingers. Easy way to track quality and amount of sleep. Keeps record so you can go back and see trends. Interesting to see possible apnea or toss/turn during the night.
I liked it for the first 4 nights and now it won’t charge. So after 4 days of use its not working correctly - wouldn’t charge. So contacted customer service and they made suggestions to trouble shoot. And this solved the issue.
Good sleep is essential to brain health. By tracking your sleep patterns, you are insuring against potential long term health problems. As they say, an ounce of prevention is worth a pound of cure.
