The Oura Ring 3 is almost as good as the brand's new Oura Ring 4. What the Oura Ring 3 lacks in novelty, though, it makes up for with a great Black Friday deal of up to $100 off.

If you've been waiting for Black Friday to snag a deal on a smart ring and give it a try, you're in luck. While neither Samsung nor Oura is offering major discounts on their smart rings, there's one standout option for those looking for an affordable yet feature-packed option: the Amazfit Helio Ring.

The smart ring segment has grown by leaps and bounds over the past few years. Once a category dominated almost entirely by Oura, new releases from companies like Ultrahuman, RingConn, and even Samsung have introduced serious competition into the market.

Over the last year, I’ve tested tons of smart cameras, sensors, and robots of every kind, and I’ve found some favorites. Here are my favorite smart tech devices from past year that I’d recommend buying while they're on sale for Black Friday.
