I am thinking of getting a fitbit and was wondering who has one and what do you think of it ? love it hate it? I would love to know before I make my choice thanks

1) Is there a similar device that also monitors heart rate?

2) how does it really really track activity level?? If I bike 100km how can it know that i'm biking?

sorry-don't know those answers. I know when I use the bike at the gym I remember how many minutes I am on it and record it and also record the machines I use.

I thought this all tied in with myFitnessPal? Am I wrong?

Seems like they're trying to compete with the nike powerband...

How much will this cost?
