What Customers Say

The Forerunner 255 impressed reviewers with accurate GPS and heart‑rate data and a good selection of running and triathlon modes, and they found the battery lasts up to two weeks on a single charge. The watch is lightweight and comfortable, and it introduces the latest Garmin Elevate sensor. On the downside, there is no touchscreen, so users must navigate with buttons, and features like music storage, ECG and Training Readiness are missing. Smartwatch capabilities remain limited. It’s a solid training watch for athletes who can live without music and advanced smart functions.
