Negative Positive
Title: works inconsistently after 4 months use - April 11, 2009
Review: D. Baker's experience on April 1, 2008 mirrors my own. After maintaining 115 to 120 heart rate on the treadmill it drops to 50 and then to 35. I checked manually and that low count was wrong. Now it goes back for a refund I hope. I don't have the original packaging unfortunately.
Is the review positive or negative?
