Top complaints
Oura Ring 4
- Battery and reliability problems
Amazon's review summary says battery life is mixed, with some owners charging daily or every two days, and that some rings stop working properly or break within a year. WIRED's reviewer saw dwindling battery life on his silver Ring 4.
- Expensive, and most data needs a membership
Wirecutter and PCMag both flag the $349-and-up price and the $6-a-month membership needed for most data. Amazon owners call value for money negative.
- Logs rest as sleep; scuffs
Wirecutter says it regularly mistakes rest such as computer work or watching a movie for a nap, and a colleague's ring logged wake-up times late. WIRED's reviewer saw scuffing on the silver finish, but not on the ceramic version.
RingConn Gen 2
- Battery stops holding a charge; rings stop working
Amazon's review summary says some owners report the battery stops holding a charge and the ring stops working after a few months, and calls durability a concern.
- Few workout modes
Tom's Guide notes it tracks a relatively modest number of activities, such as running, cycling and yoga.
- Mostly a secondary recommendation
WIRED lists it as an honorable mention, mainly $100 more than the Gen 2 Air for sleep apnea monitoring, VO2 max and titanium. Amazon owners are split on whether it's worth the price.
