  • Works for me with Weight Watchers

    I am new to having Fitbit. So I wanted something easy. This meets my needs. I also like that I can wear it swimming. Flex 2 seems to be the only one that is waterproof. I am on Weight Watchers. It was each to sync Flex and WW. Today I learned from WW that I don't have to manually put in activities anymore. The Flex is doing all the activity stuff.

    Not content with the product because it delays on the step count as well as adding the miles. The price wasn't a bad deal, I wish I was able to return it. Unfortunately my 30 days passed.
