Anybody here used the fitsense distance & HR monitor for running? I'm interested in something like this or the new Timex GPS with HR, but the Fitsense is cheaper and you don't have to wear that thing on your arm (just a pod on your shoe).

I'm sure it's not as accurate as a GPS system, but I'm curious as to your experience to it's accuracy, reliability, ease of use, etc.
