Very impressed with this ring for the price. Read more

You can't beat this quality and price. I bought this because my wife got tired of me wearing my watch to bed to measure my sleep score. This was the perfect solution. Comfortable, true to size and accurate readings. The battery seems to be long lasting and simple to pair to your phone. Would not hesitate to purchase. Read more

Excellent value for the money. Very fast charging speed. Takes not time at all. Sets up easily on the app. Love the sleep tracking and the other features. Pretty durable too. Had this ring for almost 2 months and still very happy with my purchase. Read more

These days everything we own can track some aspect of our health. I love the looks of this ring, and it's fairly comfortable. I has several functions of tracking sleep, heart rate, etc. It says it's waterproof, which is good. I'm sure this is a feat of engineering to get all these functions in to a small elegant ring. But for the price, I feel like it should do more. I realize that is possibly the most entitled I've ever sounded in my life, but hey, it is what it is. Full disclosure, I could not wear it for long. I ordered a size that fits my left hand, ring finger. My right hand is a size larger, and all my fingers swell throughout the day, so I tried to use it but after a couple hours, my fingers became too tight to continue to use it. In all honesty, my phone and my watch do all this ring can do any way. If you need a no nonsense way to track the basics of your health and sleep, then this could be the item for you! It's a good product. It's a nice item. It's beautiful, and comfortable. But it's not for me. It looks like a good app included though, lots of function-ability with sleep tracking and all that. Included are a few random screen shots of the app. Read more

This smart ring is a neat accessory to track activity and vital statistics. It is recommended to wear this ring on your pointing finger or your middle finger for the most accurate heart rate and blood oxygen readings, so you would want to measure the ring size accordingly for the proper fit. It comes with a magnetic usb charging cord as well as a clam-shell case that has an internal battery that can also charge the ring. It doesn't take much time at all for this ring to fully charge and a charge can last 4 to 5 days before needing a recharge. The ring is a flat band with a shiny stainless steel finish that looks simple and classy. The inside of the ring has the battery and electronics encased in plastic. So far the ring has been quite durable and works well most of the time. After a couple of days wearing the ring it stopped transmitting new data to the app, however it was still connected. I found that it began working correctly after updating the firmware from the app. Another time it stopped transmitting data, I found that it needed to be connected to the charger to wake it up and then it began working again. This ring seems to be accurate, however I don't have anything else to compare the heart rate or footsteps against, so I assume it is telling me the truth or close to it. The one thing that I found interesting is that the app does not have access to transmit data to Google fit or other health tracking apps, so it is purely informational; I suspect that this feature could be updated in the app over time. Overall I really like this ring and it is more comfortable to wear over a health tracking smart watch. It fits well and looks nice. Read more

My wife got another brand of a similar ring. I used the sizing, and it worked out great! I suggest following the sizing guidelines! The instructions show a charging cable that's different than what I received. It's an upgrade from what I can see. Charging instructions say the light goes green when charged ... I let it charge for several hours, light never went green. I installed the app on my iPhone, put on the ring. It takes a few days for data to start making sense. This is true for any ring of this nature. There's a "right" way to wear the ring, meaning, it's supposed to sit in a specific spot to it can read from the internal part of the joint of your ring finger (non-dominant hand is recommended). I've worn a wedding ring for decades. I still notice this from time to time. It's much thicker than my wedding ring. I'm thinking about using some of my wife's finger nail polish on the underside so that I know where the sensors are (you can't see that when you're wearing it). Then I'll know if it's spun off where it's supposed to be. I haven't tried wearing it in the "wrong" position, although that's to come. I will see if the readings vary. I was concerned about battery life. I went 3 days and it used maybe 20%? or less? Long term results may vary. I did turn on more functions on day (1st part of the day), & after 48 hours the battery life consumption seemed about the same. Which makes me happy! It's a snug fit. I use a little lotion to get it off easily. I've used this in the shower, but just don't really like doing that. My iWatch can withstand a shower, I just don't like getting electronics wet. The measurements of step, heart rate, etc. match my iWatch within 10%. I'm not looking for perfect, rather trends. This does that well, which makes it a great value for the return on investment. Definitely much cheaper than an iWatch, while giving basically the same readings. Glad to have this in my electronics arsenal! Read more
