The Oura Ring 4 is still at its lowest price ever for Black Friday

The newest Oura Ring 4 is still available from Amazon, Best Buy, and Oura for $249 - its lowest price to date - for Black Friday, which is about $100 off the standard retail price. Or you can save up to $150 if you're going for the gold or rose gold models, since those are down from $500 to $350. That's if you fancy.

The Oura Ring 4 is best known for its advanced sleep tracking, and I've found it pretty useful even though I don't really like spending $5.99 a month to get the most out of the subscription. That subscription gives you more detailed sleep tracking, 24/7 heart rate data, temperature monitoring, SpO2 sensing, and more. It's all the stuff you'd want monitored in case something gets out of whack. The latest Oura 4 model improves tracking of oxygen levels, your heart rate, and activities.

Don't sleep on the deal. Ha ha. See what I did there? Sleeping gadget. Anyway, where was I?
