Right now the Oura Ring 3 is just $349 at Amazon ahead of Black Friday. That's $100 off one of the best smart rings we've tested and the lowest price we've seen yet. The retail and sale prices vary between colors and Horizon and Heritage editions of the Oura Ring 3, so here are my favorite deals below.

Best Buy’s pre-Black Friday deal taking $200 off the price of the Oura Ring Gen3 Horizon — a price drop of over 36% — is a limited-time offer, and a great opportunity to discover the benefits of this small yet powerful health tracker.

If a smartwatch is too bulky or complicated, this sleek, 'set-it-and-forget-it' health tracker might be just the ticket.
