3/5: I really wanted to keep this ring cause it fits well, the battery is great and it's pretty accurate but after two weeks of use, I've come to realize the ring is just too bulky for me and I really don't like the black color when all my other jewelry is silver plus the app has one major flaw, that it doesn't show you your step count per each hour of the day it just shows a step count for the day, so unfortunately I will be returning. 2/24: Was super easy to set up with the app downloaded from the play store and stays connected to it. Battery lasts about 5-6 days, which is great. The app works well and you can change the unit settings. Pretty accurate readings when compared to my Galaxy watch. I love the touch sensor section on the ring. I only wish it came in silver.

I've purchased two of these the other one was for my brother and for some reason I have to charge it every twenty minutes. It started out excellent until the app update.

Updated - after 2 months. The battery requires charging everyday or 1.5 days. If I had know this sooner I would have returned - no to late. Score of 1Size - was correct. I had purchased a Ring Sizer and it gave me an accurate measurement. Smart Ring fit with no problems from the first time I put it on my finger. This part was 10.Set-up - easy. Had preloaded AIZO Ring app so total set-up time was about 5 - 7 minutes. This part is a 5.App - this has good information well organized. I personally find it very helpful and easy to understand. This part is a 4 (Software in my opinion can never be a 5).Result is a rating of 4.Full disclosure - I am long time Fitbit user - first one in 2015 - who finally went to a Smart Ring and I love having a free wrist again.

The ring fits well and is comfortable. My primary concern was for sleep monitoring, which has been an issue in the past with other devices that needed to be charged overnight, but the charge on the ring lasts for days!

The ring was not new, it was used, the package was and old box all beat up, the tapes sealing the box were old and not really sealed the box completely. The charger was full of dust, the ring was only 25% charged and it took 2 days to charge it to 85%. I bought another ring for my brother, and his ring was new, totally different experience and different product.

Battery does not last 5 days!

Very happy with the product

upd: unable to connect with the app at all!The ring has unique shape (not a solid circle inside) and quality materials.The app (JC Ring) could be better. It has a nice functionality but interface could be polished.I like the fact that the ring can actually read naps and daytime sleep.
