Has anyone tried the fitbit I want to buy one but not sure if I should invest in one thanks.

I love my fitbit. I'm addicted to it! Best investment for me!

Love mine. I wear every day. I wear it on my bra. I record all my foods and exercises.

Also look at the UP by jawbone. I like it because you wear as a bracelet. The fitbit was too small for me, I'd lose it

I have the Fitbit One...and love it. It helps me to see when I need to pick up my pace with exercise, and keeps me honest with calories on a daily basis.

I have seen the ones you wear as a bracelet, and was not impressed. My son has one, and it looks good on him.

I have small bone structure with my extremities, and it was far too cumbersome for me. Also, unless you want to look like you are off to the gym all the time, not the "fashion statement" you might want to choose.

Others mileage may vary...

I also have fitbit one... I have lost and rediscovered it a few times, but it is small enough to be inconspicuous. I use it with MFP!

The Fitbit flex you can wear as a barcelet too here is the link http://www.fitbit.com/flex This will be my 30th birthday present to myself but I am taking donations
