  • Easy for older eyes

    As my eyes get older, the use of a small watch face without my reading glasses is next to impossible. By switching to the ring, I am able to gather the same data for the most part and just dump it directly into my phone.

    The product is good but the store only has limited amounts I needed a size 12 or 13. They only had size 11. I purchased it and have regretted it ever since. Also note there is a year or monthly fee. Yearly $69.00 which was not really realized at time of purchase. I have since cancelled this service. Use it as a pinky ring!
