Review: Great ring, very happy - I have been using the ring for a couple of weeks now and it has exceeded my expectations. It has so many extra features I didn even know about and the caffeine window is so helpful. I love the fact that based on the day before, it will make suggestions for the next day on sleep, exercise etc. Can highly recommend 😀
Review: Too many bugs to deal with - Updated after owning for a month. Really not sure if this ring is worth it. In a month of owning it I’ve had two major issues that I’ve had to go to support for - 1) ring disconnected out of nowhere for no reason, had to completely remove it from my account and reconnect it. 2) my fully charged battery now dies in less than 12 hours. They’ve got some serious bugs and issues to sort out. If I encounter another issue I’m going to be requesting a replacement or refund. - So far so good! I’ve only had my ring for a few weeks but so far I’m enjoying it. I find the app experience to be detailed and helpful, and easy to navigate. The ring fits well and feels quite durable. The functionality seems to be doing everything I’d like it do, albeit it’s still in calibration mode. Looking forward to seeing how useful it is moving forward!

The sleep information is good but the heart rate is way too high compared to a reputable BP machine and even an oximetre!!
