RW VERDICT If it weren’t for the less than stellar Garmin Connect app, the Forerunner 935 would have received full marks. From the uber-comfy design through to the reliability of the data, everything just worked. Battery life was awesome, satellite locked on in under 30 seconds every time, the accelerometer kicked in nicely on the treadmill with none of the usual drifting in and out and – for triathletes – the sensitivity of the swim metric sensors was a cut above anything else we’ve tried.
