Negative Positive
Title: Doesn't work
Review: I bought this item a few weeks ago and have used it 4 - 5 times. The heart rate monitor works for about 10 minutes and then the signal is lost. I can pause it, reposition the monitor, find the signal and then start it again but it quits again and again. I'm going to try to replace the battery in the monitor but I don't know why the battery would be weak already. I think it is more likely the battery compartment is getting wet from sweat. Why doesn't the manufacturer put the battery compartment on the front away from the body? No one sees the monitor anyway.
Is the review positive or negative?
