    • Great smart ring even survived the washing machine! Great smart ring even survived the washing machine!
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

Review Image by NATHACHA
LA INFORMACIÓN QUE DAN SOBRE LAS TALLAS NO SON PRECISAS, me tomé las medidas, tal como indican y pedí el anillo con la talla que salió y me queda extremadamente grande. No puedo usarlo, porque se me sale. YO LO QUERÍA USAR EN EL DEDO ÍNDICE, pero hasta en el dedo pulgar me queda enorme. Lo peor de todo es que para la devolución del dinero, hay que mandar llevar el producto a un establecimiento en EUA y yo no vivo en Estados Unidos. Lo cual se me hace imposible. NO RECOMIENDO ESTE ANILLO. Perdí mi dinero y tiempo esperando este anillo y ahora ni el dueño de la tienda se contacta conmigo. Lo cual habla pésimo de la tienda, el servicio al cliente es nulo. ME BASÉ EN SU TABLA DE MEDIDAS Y PEDÍ LOS ANILLOS APILABLES CON CIRCONES Y AHORA ESO TAMBIÉN ME VA A LLEGAR MAL POR CULPA DE ESTA TIENDA. ... show more

    • 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 Inexpensive smart ring tracker but needs some improvements
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

    • Good intro, but there are much better options out there.
So this was my intro in to the world of smart rings. When I was still on iPhone, I was pleasantly surprised to find that this ring actually worked with Apple Health. However, upon switching to Android, no health connect integration at all. Only third party service it works with on Android is Wechat Sports, which here in the U.S isn't really a thing. Also, on the Android side, I can't speak to how the app looks visually, but using a screen reader, the app is a mess. Would recommend if you want to see if a smart ring is something you would like, get one of these and wear for a few months before spending big money on one of the better brands, but take any metrics it gives with a grain of salt. ... show more

Much smaller than I thought it would be. I would suggest sizing up. Can't wait to see how it works for sleep and such.

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
