I ordered three rings I ordered three rings. One of the ring size was not accurate. There’s no way to return the ring. I was told that I cannot return the ring because I chose the size. Please note an American seven fits me perfect this particular rain fits on my pinky finger horrible horrible service

RingConn is an excellent piece of tech RingConn is an excellent piece of equipment. That product does an incredible job and my wife is so happy. So why only three stars, ordered this over a month before it was needed, the size rings turned up 10 days of ordering, order the size with two days, had to double check with an email as it was not clear it had been order. Then if took three weeks to arrive from of all places, China. It arrived over two weeks late but had been sold as a US piece of technology. Not impressed it was a gift with plenty of time to arrive.

Great value for money with some tweaks needed here and there The whole pipeline from receiving the size kit to the actually ring was super smooth! The ring itself is very robust! Using it for more than 3 months now, I haven’t experienced any issues! The app is constantly improving to include new features! Great sleep tracking but the steps counter algorithm could use some refinement! It counts more steps than it should. Overall very good experience so far and great value for money!

Trully outstanding ! Trully outstanding ! First one i receive was bornes and They replace it with no stupid question super app on iPhone work super good Fit super well and confortable too wear all day long and i dont Like wear ring. Only complain is The black finish that Wear off rapidly (should take silver)

Great tool to monitor my health I have been able to use the information on the app to understand how things are working with my CPAP. Also, after a recent surgery to see how low my O2 level was during the night after the surgery. I wish you had put a mark on the outside of the right that shows it is positioned correctly for reading. I tried myself, but nothing seems to stay on the coating. If there was a mark on the outside of the ring that would be towards the palm of your hand it would be easy to know that it had not twisted around too far.
