What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Bright, high-contrast 1.2-inch AMOLED display that remains readable in direct sunlight and looks sharp at 390x390 pixels
- Five physical buttons plus touchscreen allow reliable input during exercise, in cold weather, or with gloves on
- Battery life holds up well in real-world use — always-on display yields around four to five days with daily GPS activity recording
Reviewers push back
- Single-band GPS only — no multi-band or dual-frequency option, which the next model up in the line provides
- No triathlon multi-sport mode, an odd omission given the watch targets active athletes including swimmers and cyclists
- Fourth-generation optical heart rate sensor can lag slightly when heart rate drops quickly after intense efforts, and lacks ECG capability
Reviewers broadly agree the Forerunner 165 is a capable, well-rounded running watch with a vivid AMOLED display, solid battery life, and deep training metrics that punch above its position in Garmin's lineup.
Reviewers praise
- Exceptionally bright 3000-nit display excels in outdoor conditions and powers impressive flashlight functionality
- Double-tap gesture works reliably and becomes genuinely useful once adopted, especially for music and call control
- Excellent battery life delivers 36 hours of normal use, 72 hours with low-power mode
Reviewers push back
- Visually indistinguishable from the original Ultra, making the upgrade feel pointless for existing owners
- Action button is underutilized—reviewers consistently forget it exists or rarely press it
- Blood oxygen sensing removed on newer units due to legal issues, though hardware may still be present
The Ultra 2 is a minimal spec bump over the original Ultra, distinguished mainly by brighter display and double-tap gesture, making it worthwhile only for first-time buyers or those with very old watches.
Where reviewers split on Forerunner 165: GPS accuracy without multi-band: DC Rainmaker found single-band GPS 'working just great' and considered the omission minor; DesFit echoed this optimism, while PlayBetter flagged it as a clear step down from the higher models without testing it directly On Watch Ultra 2: Black titanium finish—one reviewer loves the matte look and orange accents, another worries about long-term durability of the coating
