I love that it doesn’t require a subscription, and the battery lasts for several days
I received the Smart Ring Fitness Tracker well-packaged and in perfect condition.From the start, you can tell it’s made with high-quality materials, and the Champagne Gold color looks elegant and modern. It works exactly as described — accurately tracking heart rate, blood oxygen, blood pressure, sleep, and steps. Pairing with my iPhone was quick and easy. I love that it doesn’t require a subscription, and the battery lasts for several days. An excellent purchase — highly recommended!

Not too bad…
Been wearing this ring for about a week. I also wear an Apple Watch. This ring does get my step count higher than my watch, but that’s no big deal. I did notice though that it consistently measures my BP as being somewhat high. Started to make me nervous since I have never had high BP. Nervous enough to buy a new BP monitor. Ring said 134/85 and cuff monitor said 96/59! LOL! So while this ring is a good tool, just take its readings with a grain of salt and maybe check some of its readings in other ways.

Review of ring
It was shipped instantly, arrived on time. DIfficulty getting this to hook up at first through my wifi network but finally did. I wasn’t keen on the user interface and it really didn’t offer more data than I’m already getting on my apple watch. I thought it would do real live tracking and I had to activate the “start” command each time to take BPM. So, not to keen on keeping this one and will look for Ultrahuman or something that still doesn’t require a subscription. If one wants a simple report, minimal data, this is probably good for you.

Better than oura – no subscription required!
I’m so glad I got this. I was about to buy the Oura ring but couldn’t justify the monthly fee. This one does everything I need — tracks my heart rate, sleep, blood pressure, workouts — and NO subscription. Just a one-time buy and done. The app is super easy to use, battery life is solid, and it charges fast. I’ve even used it to take pics with my phone, which was kinda fun lol. Definitely recommend measuring your finger first though, I almost guessed and that would’ve been dumb. Love this thing. I feel like I’m finally paying attention to my health without paying extra every month

Stopped holding a charge after two months
Worked well for about two months, then it stopped holding a charge. It would say it was charged 100% but the charge wouldn’t even last for 6 hours which made it basically useless to track anything.I sent a message to the company through the app but never received a response. Very disappointed.

Best Buy!
Love this! Measures well and stays charged for at least a week. I have a friend that bought the $400 ring and she like mine better. It shows every scratch but still doesn’t look terrible. Definitely worth the money.
