Product 2: Garmin Forerunner 570
3.2

Battery life is the biggest tradeoff. Some reviewers still found it good in normal use, but many say the brighter screen makes it noticeably weaker than the 265, especially with always-on display.

4.2

Heart-rate accuracy is a recurring strength, though one first-run test saw an elevated max reading and another reviewer noted occasional quirks.

Product 2: Garmin Forerunner 570
4.6

Heart-rate tracking is a major strength. Multiple reviewers say it stays close to chest straps, performs well in intervals, and is one of Garmin’s better recent sensors.

materials quality
Product 1: Polar Pacer
3.7

Materials feel practical and durable enough, but the mostly plastic build can also come across as basic or toy-like.

Product 2: Garmin Forerunner 570
4.4

Material choices are a step up from older mid-range Forerunners, especially the aluminum bezel and sturdier-feeling case construction.
