How is the Ultrahuman ring? Considering to buy one, feedback pls?

I am planning to buy this after hearing a lot of good things online, does anyone have any first hand experience of using it and how beneficial this actually is. How different is this from other smart watches and band available online Link : https://www.ultrahuman.com/ring/buy/in/

Has anyone used ultrahuman ring and what is your review on same ? worth investing or waste PS : asking about their ring not GCM Monitor

Its super costly, but I do believe it can cause my quality of life and health to improve a lot

I am thinking of buying the Ultrahuman Ring for tracking my health and sleep data. Has anyone here tried it? Need feedback on its accuracy and meaningful insights that it can provide.

Hi all, I am looking to sell my Ultrahuman ring. I bought it a few months back but I realized that it is redundant for my lifestyle as I already have an Apple Watch to keep track of my fitness. Don't get me wrong, the ring is pretty good to keep track of overall lifestyle (sleep, stress, caffeine intake, etc), but not great to keep track of exercises. DM me here or ping me on telegram @i_am_machine123 if you are interested in buying.

Seems like Ultrahuman had started focusing on the US market (because India is saturated after a point). Oura must've sued them to limit competition, and because a lot of things were too similar. Anyone knows more here?

Thoughts on this ongoing saga?
