Cheap Polar F Blue Ice Size Small Inch Transmitter Heart Rate Monitor for Women Great for Weight Loss and Cardio Exercise

I've had the Polar F4 watch for 5 months now and I use it regularly. I would say it's OK for basically knowing where your heart rate is when exercising, but it could use some enhancements, such as: a back light (helpful when you take an exercise class in a room with the lights dimmed - spinning, yoga, etc); ability to check your heart rate and not have it counted towards your weekly exercise totals; ability to delete a bad / erroneous heart rate reading. What I mean for the last two is the watch only records your heart rate when you engage it in exercise mode. Once it's in exercise mode for more than 5 seconds, that reading counts. That session and its duration and heart rate reading are added to your weekly totals. Well sometimes I don't want to add a heart rate reading toward my totals. But there's no option for deleting it or not saving it. A useful reason for having the ability to check your heart rate reading without having it count towards your exercise totals is to get a reading of your resting heart rate, when you are not exercising. You can use your resting heart rate as a basis to calculate your maximum target heart rate.
Another issue is that lately the watch a) freezes up and doesn't respond to the buttons and b)doesn't read my heart rate at all or stops reading it mid way in the middle of an exercise session. I can't understand why because I make sure the chest belt is secured in place and I'll repeatedly even tighten it and press and hold the chest belt to my chest. This is annoying because I have to pay more attention to what the watch is doing than paying attention to the exercise class - defeats the purpose of exercising. This only started happening when I started using the watch 5 to 7 days/ week, ironically when I need it most. In summary, I would say it's an OK watch if you are not relaying heavily on the readings. But if you do and you need it 7 days/week at high intensity workouts, look into getting a more advanced model.
