I was selected as an “Epson Runner” to review the Epson Runsense SF-810. In exchange for 5 video reviews I’ll be allowed to keep the watch, but that’s not going to stop me being honest about the device and my experiences.

Some key points from my findings on the GPS accuracy

• The GPS does seem very accurate, especially compared to the Garmin Forerunner 220
• The usage of GPS for pace and speed on the device is excellent
• The AGPS feature to push GPS satellite information results in a fast GPS lock, but its VERY slow without it
• If the bluetooth communication with the device was “Always on” this would be an improvement
