Has anyone ordered a Polar FT4 HRM from Amazon?

I'm trying to order the pink/purple Polar ft4 heart rate monitor from Amazon but there is no option to pick the size of your chest strap, unlike on heartratemonitorsusa.com, where there are 3 sizing options. Is the chest strap from Amazon just a universal size that should fit anyone? Has anyone had any problems with the chest strap sizing after buying off Amazon?
