I bought this to test out smart rings and i love it. I track my steps and sleep daily, even hourly, and monitor my daiky routine and this has made me much more aware and active! The ring lasts 8-9 days and it only takes 2-3 hours ro recharge it for the next week. The app is great and informative and I absolutely love this Qalo product! The ring covers are also a great feature to wear when working out and swimming.

Received in time but have not been able to recharge after first use .. waste of my money since they say it’s beyond the returnable time and I’ve had it less than 30 days. Tried to get online help from Best Buy with no success. Also contacted the vendor with no response at the time as well.

I have enjoyed my "current" smart ring. There are times that I don't want to wear my @pple w@tch- I am a Swatch watch collector- and the Slim QRNT gives me a good alternative to collect my health data.
