Which have you guys had most success with?
I'm conflicted on which to get. I like that newer (Fitbit one?) calculates BMR, measures sleep cycles and can be synced, as well as worn like a bracelet and waterproof. I also know some people have had success with the Activelink and it works well for WW but I think if I got it it might end up going through the wash. I think I heard the NikeFuel Band measures heart rate which is something I'm looking for.
I dunno.
What has worked for you all?
