LYNX Smart Ring

This ring must be defective. It does not capture sleep data. Accuracy is a major concern. The exercise feature is constantly having connectivity issues to where the app pauses or just stops the exercise to where i have to manually restart. Ive tried everything to fix the issues and it still does not work. Accuracy is also a major concern. I want to return the product for a refund

The RENPHO Smart Ring is stylish and lite, it tracks more than I was expecting. It sync’s to my iPhone. All good for now, time will tell.

I love my ring. The one issue I am having is that I need a new charger case and you cant easily replace it. I havet been able to use it because i cant charge it. Hopefully they will send me a new one but you should be able to buy an extra one easily. Thats the only negative issue I have but its a big one.
