As someone who's always on a budget but values quality this ring from Hunan Constant Li has been a pleasant surprise I've been using it for over six months now and it's become a part of my daily routine I love how it monitors everything from my heart to my sleep patterns without any extra fees the design is sleek and it goes with all my outfits from gardening clothes to something more formal for work the waterproof feature is fantastic I don't have to worry about it when I'm washing hands or caught in the rain although I wish the accuracy was a bit better during high-intensity activities overall it's a solid choice for keeping an eye on my health without breaking the bank
- Pros: I finally found a ring that tracks my health without looking like a gadget it fits my style perfectly and the battery lasts so long I barely think about charging it the sleep insights are eye-opening and it works great in water which is a huge plus for my active days
- Cons: It could be wrong sometimes with the heart rate readings especially during intense workouts and the app interface feels a bit clunky at times which is annoying for someone who uses tech a lot
