The listing, Polar FT4F Purple/Pink Heart Rate Monitor - BNIB has ended.
I have for you here a BINB Polar FT4F Purple/Pink Heart Rate Monitor
I set up the watch when I purchased it but didn't get any further than that. However, once you do that the screen stays on permanently, so it's unused, but the battery is dead which is why you can't see the screen lit up in the images. Doh!!
It takes those small flat 3V batteries. Should be able to find them at your local store, or of course you can always purchase them on line.
