## Customer Reviews

### ⭐⭐⭐⭐⭐ Great smart ring
*by A***Y on March 20, 2025*

Love this ring! I got it to track my cycle because I have PCOS. It's very easy to use. The battery on it is great. I love that I can see how I slept and what to except in my cycle.

### ⭐⭐⭐⭐⭐ Easy to wear and helpful!
*by S***S on April 16, 2025*

I purchased this ring after having some health issues and needed a way to track my heart rate without breaking the bank. I love this ring and it is sleek and does not bother me during the day and sleeping.

### ⭐⭐⭐⭐ Not for perimenopause tracking. Get the sizing kit
*by G***N on April 8, 2025*

This didn't fit me true to size, so I suggest getting their sizing kit and making sure you have the correct size before you begin.And, just to be clear, this is very much geared towards women trying to get pregnant. I thought the features would be just as useful for tracking perimenopause, but unfortunately it's just really not useful for that at all, so I am back to manually tracking with my GCal app.I do think the app and tracking capabilities seem to work well and would have been very useful for fertility tracking for pregnancy.
