Title: Great ring
Review: Ring works perfectly. The battery lasts between 4-5 days and the ring itself is comfortable. The ap works well and measures your pulse, blood pressure, sleep and oxygen level. It appears to be fairly accurate given its taking measurements from your finger. I use it on my ring finger.

Title: Nice tracker
Review: Great little tracker for the price. Shows me all the info I care about and it’s totally convenient to wear (much preferred to wearing a watch style). Just be careful with sizing I ordered a size 6 which is exactly the size for the finger I wanted to wear it on and it was too small. Not sure if it’s the ring design or a sizing issue but just take note before ordering you might want to upsize.

Title: Not for Blood Pressure! Good pulse, step and sleep monitor
Review: 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.

Title: Size up 2 sizes or it won’t fit
Review: 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.

Title: An awesome smart ring!
Review: 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.

Title: Got the wrong size
Review: Ring runs smaller than expected. I wanted it for my index or middle finger so bought a size 7 which normally fits, but this did not. It came with a ring sizer that shows I should have bought a size 8 (but I do not want to buy again and then have that one feel too small as well). Live and learn. I wear it on my ring finger and have found that the readings it takes (like blood pressure) have been fairly accurate. Battery life so far is lasting for several days. I love the color (the determining factor for why chose this ring). The reason for three stars is that the ring ended up fitting so much smaller than anticipated.

Title: Great Value for Money!!
Review: I am amazed at the quality of this ring! It’s a fraction of the price of the Oura ring, doesn’t require a subscription, and is waterproof. It has been comfortable to wear, came in the right size and looks stylish. The app works perfectly, I have had no issues with it.

Title: Less expensive doesn’t mean cheap!
Review: I’m floored. I bought this for myself because my Apple Watch doesn’t do blood pressure, blood oxygen or sleep. Also I can’t wear watches at work. I’m over the moon happy with this ring. The accuracy for heart rate and step count are on par with my Apple Watch and pedometer. Downloaded the app from the App Store and connected the ring with zero issues, chose to allow it to update my health data and its all good.The ring itself fits good, I read the reviews ahead of time and used a plastic ring sizer and when I ordered went up instead of down on the half size so it fits comfortably. I suspect it needs to be a bit snug on purpose to get more accurate readings.To get the best blood pressure monitoring have someone take your blood pressure manually and set up in the software according to the product manual. It’s very accurate once you set it up.Comes with three silicone bands to wear over it so you don’t scratch it up during work or exercise. I find it more comfortable to leave the silicone band over it while sleeping too. Seems pretty durable so far but I’ve only had it a few days. Battery life is outstanding, I changed it to read my heart rate every half hour instead of hour and I expected to have to charge it more but so far its going strong and well over 60 percent power.
