    • It’s correct with the doctors machines. Charge last 5-6 days great seller 5 stars
Color: Lavender Pink Size: 9#
Love the color. They are not making colors no more. Ring didn’t fit with using ring sizer very kind sent a new one out a size bigger no charge. 100% great seller. App is good few hang ups but fixed he helped me very kind. Ease of use good comfort is very good. Durable . Connectivity easy but read twice and buy ring sizer for a buck. I got the ring health issues and 9 auto immunes wanted 6 blood pressure a day. I used real blood pressure cuff and the ring perfect! Oxygen perfect as the one I’ve been using long time. Ring last 5-6 days before charging its great 5 star seller which they would make the colorful ones. Great price works perfect for me.bought husband the black one and he loves it ... show more

    • Great value for a terrific tool
Color: Lavender Pink Size: 9#
Review Image by Jessalynn Heydenreich
I’m not sure why anyone would spend a few hundred on one of these devices when this one is less than $50 and works great. Readings are pretty accurate as far as I can tell. The fit is a bit odd, I ordered the first one in my standard ring size for my middle finger and when it arrived I realized the sizing is not that of a standard ring and had to go up one size. This time the fit is perfect. I really like the pink color but it has already gotten scratches on it. ... show more

    • Not for Blood Pressure! Good pulse, step and sleep monitor
I purchased this ring as it stated it takes blood pressure. However, I think it is making up the numbers. My diastolic is constantly ten points low, but the systolic is between 10-25 points too low, with no obvious metric as why it is not accurate. You also have to download a shady app to use this. Everything else seems fine; pulse is accurate, sleep monitoring and steps. It does look sharp too. ... show more

    • Size up 2 sizes or it won’t fit
Color: Orange Size: 9#
Review Image by Susan
The sizing is so far off I’m now returning my 2nd try. If you use the measurements from the photos to size go up at least 2 sizes. I was supposed to be a size 8. It didn’t fit over my knuckle. I got a size 9 and it fits but it’s too tight to read anything. I’ll now order a size 10 and hope for the best. I ordered my husband 2 different sizes and the 2nd size fit thank god. I’m sick of returning these things. At least the shipping is fast. It is annoying I have to print a label for returns instead of being offered a QR code. This is my 2nd ring using this tracker app. I’ve lost weight so the 1st one is too loose now. About the app: it’s just meh okay it does track your steps and your blood pressure and sleep but it has a lot of glitches. There are some nights I know I’ve woken up at least 3 times gotten up and gone back to bed and it says I never woke up. There are other nights I’ve been in bed at 11pm woken up at 5 and gone back to bed and it says I only slept from 5-7am. The app is free, which is also a bonus. It’s the only thing keeping me from dropping a few hundred dollars on the expensive ring. I’m not paying for an app that will do what my Apple Watch does for free. My previous ring was the pretty white one with flowers. Until I lost weight it was doing great until recently. It stopped tracking accurately. Which I only had it about 3-4 months ago so I guess you get what you pay for with that model. Not sure how well the metal will last with scratching. I’ve seen the orange,green,silver and Black all in person and they all look beautiful. So style wise they are decent looking. They don’t look or feel cheap they feel well made. I took off a star because of the sizing. I don’t know how other people don’t return this more often. ... show more

    • Quality and Accuracy for a good price!
Color: Black Size: 14#
I lost this ring and bought another one double the price because I like gold color. I was however so disappointed it could not match this smart ring - which I must commend for accuracy and beauty; especially with blood pressure measurements. I'll definitely be buying another one of this! I only wish they sold it I gold. ... show more

    • Good, room for improvement
Color: Silver Size: 12#
Review Image by Leah
Ring does what it says, but it doesn’t connect to Apple health. Shows that my blood pressure has been taken everyday, but there’s no value in data in health. Aldi, the battery doesn’t show in my battery widget so I don’t know what the battery life is without opening the app. I find that it is true to size though, unlike other reviews. It came with a ring sizer. ... show more

Blood pressure and steps is not accurate. Couldn’t wear much at work because the metal scratches and the rubber band catch everything

    • An awesome smart ring!

I'm sure everyone considering a smart ring will be at least somewhat familiar with the Aura ring, which is crazy expensive, with a monthly bill as well. This ring is 1/10 the price with no monthly bill. Both rings will suffer from the same limitations. No real way to measure blood pressure from a ring so I ignore those readings. Blood oxygen and pulse work very good, considering the amount of movement I do, as well as the dirt that gets on my hands. It is likely waterproof as I regularly shower and wash my hands while wearing it. Where it really shines is sleep monitoring. It appears to accurately measure my sleep, figuring out light and deep sleep. It also monitors blood oxygen which is great for those of us who snore or have sleep apnea. The battery lasts a solid 4 days and it comes with a nice case with a built in battery to charge it. It also came with colored silicone covers. I'm pretty happy with it, although I'd be pretty pissed if I paid $400 plus a monthly fee for it. ... show more
