Title: doesn't work for running
Review: Very disappointed. I used it for indoor stationary bikes and it worked perfectly. However, for outdoor running, it is utterly useless. It gives a reading of 0 about 1/3 of the times; and then would go from 90 to 170 in two seconds, or go up and down in a range of 100 and 230 all the time. According to this reading, I guess I should be ushered into an emergency room right away....
