Perfect smart ring for health tracking!
I am in love with this brand and this ring! I have another version of this and it worked well, but this newer version is amazingâesp for the price!! This ring works just as well as one that would run you hundreds of dollars. I love how it tracks my steps, stress, sleep, oxygen, and now my temperature!! It is extremely accurate esp when counting my steps, heart rate and my monthly cycle. It is absolutely beautiful and I love the simplicity with a touch of sparkle. I wear a size 7 in rings & I knew I wanted to wear it on my ring finger. I ordered a 7 and it is indeed true to size. It is extremely durable, comfortable and WATERPROOF!!! That right there is a huge bonus! I love that the app for tracking is freeâno one wants to pay for a product and then turn around to pay a monthly subscription to use said product. Overall this ring is a 10/10 in my book and the most perfect everyday accessory!!

It’s very cute and subtle
I really liked this smart ring, it is very comfortable and helps you a lot if you are an athlete or simply want to be aware of your health and the best thing is that it looks very good on your finger

Was hoping for more than it is
Letâs start with the positives of the smart ring.It has a great look, it goes well with my other jewelry. You would not look at it and think it is a smart.It has a small charging case and doesnât take long to fully charge.There is a low battery notification which is nice.I didnât know it would have ring guards to keep you from scratching the ring.Now for the negatives, the data collection is inconsistent, specifically sleep. This is the main reason for my purchase. It has only captured two nights of sleep, but no additional data has been collected.The activity data is not accurate either. I have a sitting job, yet it showed me as being very active, this is not the case during my work day.It did not come with a user manual. This would be nice to have handy for troubleshooting.Overall if you arenât trying to gather your information to better improve your health then this may be the ring for you. If you are trying to improve your health this may not be the one. Ultimately, I will be returning the ring.

I have the old versions of this ring and I love those. This one is much lighter tracks temperature. Slimmer. Super durable doesnât change colors on your finger the battery lasts super long on it. True to size fit. It measures so many things. Itâs awesome. I will definitely be purchasing one for family as gifts!

Beautiful, accurate & affordable smart ring!
This ring is beautiful. I have wanted a smart ring for quite some time but couldnât justify the price. This ring has been very accurate (has been on track with my Apple Watch AND my Garmin). For the price, you truly canât go wrong with this ring. I wear a size 8 ring and was told to size up one – or if in between sizes/half sizes size up. So I ordered a size 9, and it fits perfect.
