I ditched my Oura ring, I found that it really was great at tracking sleep HRV and RHR, but the battery doesn't last and it's just expensive e-waste after a year and a half

I got really upset with Oura when they tried to have their cake and eat it with regards to charging a huge premium for what is a very cheap device and then also a monthly subscription for something that does not need any subscription. I bit the bullet and switched to a Garmin watch for longer battery life and no subscription.

I now have a device that has way more features and lasts significantly longer.
