Anyone using an older bodybugg?

Options
I have the older model with the watch display. From what I can find, it looks like those don't link the data with on here?

I was wondering if anyone else uses one and how you incorporate it in to your system?

I am waiting on my renewal subscription to process, but then figure being able to know my TDEE I could at least enter a daily exercise calorie amount to show it on here.

But would love to know other's experience with it.
