    • Great smart ring even survived the washing machine!
Color: Rose Gold Size: 8#
Review Image by Marco
I’m very happy with this smart ring. I accidentally put it in the washing machine with my clothes and, to my surprise, it still works perfectly! It tracks steps, heart rate, blood pressure, and oxygen saturation very well. The accuracy is pretty good for daily use. The battery lasts about two days, which is reasonable considering all the features. Sometimes the information doesn’t show up in the morning, but all I have to do is refresh the app a couple of times and everything syncs right away. Overall, an excellent and very practical product. Highly recommended! ... show more

    • Great Results
Color: Rose Gold Size: 7#
I absolutely love mine. Ive had it for a week & with no issues. I’ve gotten it wet multiple times while washing my hands/dishes without a problem. It was an easy set up with no subscription needed and the app is easy to navigate. Battery life typically lasts me about 4 days straight. The 3 color silicone covers are a plus. Result numbers are decent, my sleep tracking is a bit off but I wake up multiple times during the night. Blood pressure, heart rate are pretty accurate. I’ve compared my heart rate to my Apple Watch & I typically get around the same numbers. Never really put attention to the step tracking due to always using my Apple Watch for workouts. I only lose connection of the ring when the battery dies. Other than that I recommend this ring rather than spending +$500 for another brand. ... show more

    • Recommendation ehh
Color: Black Size: 9#
I've had my ring since January and it's suddenly stopped recording how I set it. When I do get it to record it resets all my information. I've had to uninstall and reinstall multiple times now and does no good.

    • Great little ring for the price.
Color: Lavender Pink Size: 7#
This is a fantastic ring for the price. I have found it tracks steps very well. It tracks your sleep really good. I track my sleep with my Apple Watch and it compares pretty well with how this little ring works. Not so much into great detail but it’s a pretty good sleep tracker. I do find that the ring will not track your naps if you nap. Or should I say, it will track your latest sleep before the days up. If you nap, it omits your night sleep and that’s gone from tracking it. That is the only thing I dislike about this ring. The blood pressure is a little off. But it works and I just know it runs a little off my norm. The ring also runs small. I am a size 5. I ordered a 6 wear it on my ring finger. Had to size up one more due to it being way too tight when my fingers swell from hot days. Definitely size up. I give this fit ring a thumbs up for the quality. It is water proof also. Definitely a good ring if it’s your first one to try out. Charges fast. Holds a charge for five days. ... show more

    • Inexpensive smart ring tracker but needs some improvements
Color: Rose Gold Size: 8#
Review Image by Queen Bee
I wish I could say I love this smart ring but it falls short in several key ways. It doesn’t accurately track my sleep which was why I bought it. It misses nights, doesn’t record full sleep hours and doesn’t record my heartrate as well as my Apple Watch does. I do like the blood pressure and O2 tracking but am also skeptical about its accuracy. The ring takes a little getting used to wearing as it’s thick and I can’t close my hand well when wearing it. The charger works quickly and I can easily top up the battery in a few minutes. The ring was easy to set up. It came with silicone covers that I’ve used a few times but don’t find them very comfortable. It’s not an Oura but it is subscription-free and less expensive. The app is very basic and it didn’t seem to sync well at first with the new Apple ios 26. I’ll keep using it in the meantime and hope that the developers work on improving how it functions. ... show more

    • Affordable and easy to use.
Fits and looks like its expensive counterpart. Runs a bit small…had to return the first one. However the first came with a sizing ring so getting e right fit for me was a breeze. Returned first and had my refund/replacement both within a week. For a more accurate blood pressure reading you will need a blood pressure cuff to calibrate the settings a few times so the ring can “learn” your readings properly. The sleep cycle is fairly accurate and has recorded my awake times. Fits comfortably and is light weight. Loving it so far. ... show more

    • 8 months isn't bad, but I expected more.
Did a pretty good job for a while. The blood pressure measurement was always off even after recalibrating, but it was nice to have the pulse rating and the steps. Unfortunately, it has recently stopped transmitting to my phone, so there's no way to download the data.

    • Must have
Color: Rose Gold Size: 6#
I’m really happy with my UniJethro Smart Ring! It looks great, feels super comfortable, and tracks all my health stats without me having to wear a bulky watch. The app is easy to use, and the battery lasts several days. I’ve been using it for sleep and activity tracking, and it’s been spot on. Plus, the price is really good for what you get — stylish, practical, and affordable! Definitely worth it! ... show more
