Epson Pulsense and Runsense
Proving that, yes, just about everybody now sells a fitness tracker, the computer printer titan Epson released the Pulsense PS-100 ($130) and PS-500 ($200). The two units are functionally identical, though the 500 comes with a screen (and a $70 price hike). These two monitors measure the basic step and sleep, and can get four to five days battery life even with the optical heart rate sensor running. They're also one of the more affordable options for monitors anywhere. If you're looking for a monitor with more, Epson also now has the Runsense SF-810, a GPS running watch with an optical heart rate sensor embedded in its backside. Yes, the printer company is all-in with fitness trackers.
