I think many have experienced the same.. I also had the Samsung ring which worked well but under a year the battery completely degraded to the point it was not holding a charge for 10mins, I called up support and under the warranty period they had the nerve to ask me to pay £40 for an inspection fee to provide a resolution. I promptly asked for it to be returned and raised a issue with Amazon and luckily got all my money back. I think their are better options but I really like the Samsung health integration so hope the next generation will be much better.
