Blood oxygen tracking drew negative evidence in older reviews because patent-dispute availability issues frustrated users who wanted the feature.

Blood oxygen tracking was generally useful and easy once working, though one reviewer needed several attempts to get an SpO2 reading.

Size options were a repeated drawback because the Ultra 2 is only offered in a large 49mm case.

Size evidence was limited to the Brilliant version being suitable for smaller wrists.

Wellness insights were mixed: Vitals and glanceable health context were useful, but Apple Health was criticized for weak interpretation and poor user-friendliness.

Wellness insights were praised when they made health data actionable, contextual, or useful for spotting broader health risks.

Bluetooth connectivity received limited but positive evidence around cycling accessory support, especially power meters.

Connected workout tracking could drop the watch connection and leave gaps, creating a Bluetooth-related caveat during GPS-linked activities.

Fit was praised in one outdoor-focused review for staying secure during daily use and activity.

Fit was mixed: some reviewers achieved a good or problem-free fit, while one struggled with the metal strap being too tight or too loose.

Workout variety was viewed as strong for mainstream training, with varied sport modes and enough running coverage for most non-specialists.
