Pros & Cons
Oura Ring 4 (2024)
Pros
- +Sizes 4 to 15 — if the Ring 5's 6-13 window excludes you, this is the Oura that fits
- +Now routinely $249 in silver or black, $100 under its own list price, for sensing that is a generation behind at most
- +Recessed sensors mean no protruding domes pressing into the finger, unlike the Circular Ring 2
- +Same app, same membership, same iOS/Android parity as the Ring 5
Cons
- −The $5.99/month membership still applies, so three years costs $458.97 even at the discounted hardware price
- −Noticeably chunkier than the Ring 5 — that is the whole reason the Ring 5 exists
- −Discounted stock is concentrated in Silver and Black; Gold and Rose Gold still list at $499
- −Warranty covers manufacturing defects only, not the scratches titanium picks up in normal wear
- −Amazon listings are per size and per colour, so the ASIN you click must match the size you actually need
