Polar transmitter
I purchased this item along with a Polar heart rate monitor. The combination enables me to maintain my heart rate within the desired range during cardio exercises. I have also observed that this transmitter works with many of the treadmills, bicycles and eliptical machines at the gym so I can monitor my heart rate on the readout panel of the machine without checking my wrist monitor.

Comfortable, but pricey!
Note: I understand from a friend that Polar USA will take back old/warn-out sensors and send you a new one for $25 or so. You might want to check into that if your looking for a replacement that is out of "Juice".

This replacement sensor is comfortable, but they sure are pricey! I personally never found the old plastic sensors un-comfortable, and if my girlfriend's dog hadn't eaten my old one out of spite, I wouldn't have bought a new one! -Recommended

Better than the original
I purchased this transmitter when a similar one I had stopped working correctly due to corrosion. This one is designed much better than the one that comes with the F11 watch. It's a pretty big investment, but I have found it to be invaluable!

Excellent Product from Polar
This is my favorite heart rate moniotor that Polar has made. Finally, no struggling to take it off....it is easy to slip on and off with the new hook design. I depend on it for accurate monitoring and it delivers. A great product.

Excellent
I bought this to replace my previous wearlink transmitter that my dog chewed up. I have to say that I am extremely pleased with this one. It is updated from the original one I received with my unit and it is more sensitive and fits more comfortable than the original wearlink. This is by far the most comfortable heartrate monitor transmitter available.
