See why everyone's getting this instead of the Oura Ring

Popular Science 

Either you've been getting late-night visits from Freddy Krueger, or the warm milk and magnesium aren't cutting it lately. Many people are turning to ring sleep trackers to help them get better shuteye, and it might be time to give in to the trend yourself. This one by Go2sleep is less than half the price of the famous Oura Ring. And its AI-powered algorithms help monitor more than just your heart rate as you sleep. Slip the Go2sleep over your finger, drift off into your mediocre-quality slumber, and the ring will monitor you all throughout the night.
