    This new ring size is much more comfortable. I forget it’s there most of the time. The battery life is longer.

    The size is perfect and fits more like a normal ring. It is not bulky and makes daily wear so much easier.

    It got thinner and more expensive. I would be fine with the latter, but unfortunately even 40% thinner, it is still far thicker than regular men rings. Maybe next time. It definitely can work for people with larger hands or longer fingers, but not for me, unfortunately

    Ring is lightweight and the color (Deep Rose) is exactly what I expected. The battery life lasts for several days and it’s an extremely comfortable fit as I wear it while sleeping since purchasing the product.

    The ring is significantly slimmer than previous versions. The only drawback is that the stress detection feature isn’t performing as expected. Aside from that, I’m very happy with the purchase overall.
