I've had an Oura since 2000 and am currently on my 2nd unit (Gen 3). I've been generally pleased but now, after about a year or so, the battery life has really gone down dramatically which may be due to the age of the unit OR the addition of new features. Unfortunately, this is a really big problem as you lose a whole night of analysis if your ring's battery dies before you wake up - even if it is just by a few minutes.
Hopefully they continue to improve the software and, even with the battery issue, I'll be one of the first to order their next Gen when it is announced.
