This Oura Ring 3 Black Friday deal is a good saving in terms of price. At £249, or £50 off for the Heritage ring in Black and Sliver, that's the lowest the Ring 3 has ever been and £100 less than the current cheapest version of the brand new Oura Ring 4.

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