There's hardly any difference between the Oura Ring 4 and Oura Ring 5 in terms of sleep tracking functionality. The key difference between the two is design based (the Ring 5 is thinner and lighter). So, while it may be marginally more discreet to wear overnight, it's not a deal breaker worth $173 in my opinion.Honestly, I've been waiting for the Ring 5 to release so I could tell all my friends to RUN to buy the Ring 4 at its lowest-ever price, and I'm not disappointed by Amazon's Prime Day deal this year.
