Bests & Worsts Reviews from Amazon

I use this device to track my walking. I walk to music that I have compiled that is 116 to 120 beats per minute. My stride length is 2.75 feet. I usually walk in 3 mile increments. I have checked this device's mileage calculation against several measured trails and it is very accurate. It weighs less than my car key and has a very sturdy clip that stays attached to my waistband. The calories burned calculation compares favorably to formulas I've used from the web. I'm very pleased with this device.
