TOMTOM RUNNER 3 GPS WATCH

Purpose: Fitness tracking Ease of use: 4/5. A few niggly things such as the watch going back to “demo” mode whenever it’s charged, so you have to reset it every time. Efficacy: 5/5. It does what it’s meant to do. It records runs perfectly, with accurate GPS mapping. The built-in heart rate monitor is accurate. Calorie burn: 5/5. Deadly accurate, and not just on a run. Because it tracks heart rate so accurately, it means that the calorie burn readings are pretty good. Improvements: 4/5. It’s a bit fragile. Matthew Savides
