Title: Polar F4 Women's Heart Rate Monitor - not working!
Review: Unfortunately I cannot say anything good about this monitor since it worked for me only once. When I tried to use the monitor the second day it would not pick up the signal from the chest belt, no matter how I tried to reposition or tighten it. Also, the initial set-up (of the watch settings) was a bit of a chore - I nearly chucked it out of the window a couple of times. I returned it for a refund . I haven't bought another one thus far - still doing research and looking for input on which one is worth an investment.
