CoreSync Smart Ring

Exactly what i wanted . It replaced my other smart ring that was a 10 but i actually needed a 12 for maximum comfort..
Fast secure shipping .. I recommend doing business with high peak

Looks good will have to test. It's a gift! Fast shipping!

It was tight, but now I know my size and will buy another one.

perfect color works excellent

Great ring absolutely love it, the color is great and very lightweight. I use the app smart health (make sure to turn on bluetooth for that app)

I like it very much

So far it's working very well.

It works really well and battery life is great. Only thing is i need to reconnect it to the app every time i open it. It's easy though. All in all a very good product.

Great

Ok

very good, impressive

I wear it a lot i love it thank you 😊

I give this one to a friend for christmas gift she loves her too

I had a very hard time finding one of these in my size but i finally did with this seller. I like getting the information this provides.

great purchase price

Love them all

It's an interesting device that is most useful for tracking steps, heart rate, and sleep. Blood pressure is not very accurate but i didn't expect it to be. For the price, it's a great value.

Looks ok, but it's a gift so i'll have to come back for the review.

The smart ring is very nice, and it reads even more data than I expected. The app is also very easy to use. The product was delivered very quickly!

The ring is just as i expected with the features it has. It also connects to an app on my phone so i can track my progress. One charge lasted 1-1/2 days. Fast shipping btw, my only negative thing to say is that it lacks information or directions. I had to call all sorts of people to help me but none of them were available. I ended up figuring it out by myself and is now working. Except the sleep data. Still haven't figured out how to use the ring to capture sleep data and sync it with the phone app. The instruction manual that came with it is very small, with smaller letters.

Perfect

The ring works perfectly. The blood pressure and heart rate measurements are slightly higher than other, more accurate, devices, but the difference is minimal.

The ring is beautiful, flawless as a piece of jewelry, but the results of the measurements are inaccurate

Works very well. Tracks sleep, steps, spo2 and heart rate. The app works well, though i did have a little trouble syncing it the first time.

The features are steps, blood pressure, sleep, %o2, and heart rate. Over all, most of them are accurate except the steps with 5% error. I recommend this ring.

I love it 👀 💗 💗 💗
