Amazfit Helio Smart Ring - Health & Fitness Tracker with Sleep, Heart Rate & Stress Monitoring | Titanium Alloy | 1.4-Hour Fast Charging | Water-Resistant for Swimming & Showering | No Subscription Needed (Size 10) | Perfect for Athletes, Fitness Enthusiasts & Health-Conscious Individuals

I know this ring isn't very popular, but for what it actually provides if your an amazfit user it's actually worth the cost if you enjoy a lot of the a.i coach features and sleeping features without having to pay the 'premium' price. Especially for the lifetime membership to the premium features alone.I usually use mine before bed, I put it on it's charger when I wake up after syncing before starting my day. I find that it's decent and reasonable when it comes to tracking.I absolutely love the more 'balanced' approach for getting the averages for Sleep tracking. The battery life tends to last about 4 days with ALL FEATURES turned ON.I find the fit comfortable, and it doesn't fall off when i sleep. Imma be honest, sometimes I forget its on in the morning especially if i'm a bit busy. So it's nice to know I got a long battery life to bypass that forgetfulness XD.As far as functionality, it does what it needs to do. I love it like I said for the above points. Especially the 'free premium' for life thing.. Could you imagine if fitbit offered something like this? Or any of the other's that actually said 'buy my ring, unlock everything for free, for life!'.You can't get better then that, especially with a company that's so passionate about their products that they literally update at least 5-8x a year from what i've been seeing. I fell in love with this company after buying a 35$ Bip 3 watch.. which when all was said and done.. I preferred over my fitbit sense, and the app involved.Since then I have bought a balance, and while waiting for the balance 2, I have actually recommended their products to actual people.. (Something we all know no one ever does.. recommend products unless it's absolutely worth bringing up. Cause let's face it ain't no one gonna be questioning you where you got a sleepers ring, watch etc especially when realistically they all look the same!).
