(checked 2026-10-10)9,313 ratings on the Silver, size 9 listing (15% 1-star, 5% 2-star).
Still sold alongside the Ring 5 and getting the same software updates, it's PCMag's Best Value pick and Wirecutter's top sleep tracker. But it's bulkier than the Ring 5, needs the same membership, and 1 in 5 Amazon ratings are 1 or 2 stars, often over battery life and rings that fail within a year.
Subscription: Required for most data: $5.99/mo or $69.99/yr; first month free (Wirecutter, PCMag)
Top complaints
- 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.
What owners love
- Accurate heart-rate and sleep data
Wirecutter calls heart-rate monitoring highly accurate and found HRV-based Stress Resilience accurate; PCMag lists accurate activity and sleep data. Tom's Guide says it proved 'mighty accurate'.
- Gentle, personalized guidance
Wirecutter found the recommendations personalized without being pushy, and the redesigned app easier to read. PCMag praises personalized health guidance.
- Same software as the Ring 5
ZDNET says it gets all the same software updates as the Ring 5 at a lower price.

What experts say
- PCMag: Best Value, 4.0 Excellent. Cons: expensive, requires a monthly fee for most features, fewer workout details than wrist trackers.
- Wirecutter: Top pick for sleep tracking (updated 2026-06-08), but costly, better with the subscription, and it sometimes confuses inactivity with sleep.
- ZDNET: Best smart ring alternative: the same software updates as the Ring 5 at a discount.
