If you have a Fit Bit Flex and have had it longer than 6 months, you may notice that the band starts to break down where you insert the Fit Bit tracker into the band. I have had mine now for 15 months and I just had to purchase my third band. If you go to the Fit Bit website, they offer them for $14.95 or 3 for $29.95. Those come in an assortment of colors and may not be ones you like. You will also be charged for shipping.
A better option is to go to Amazon.com and buy them from a 3rd party dealer there. I recently bought a Fit Bit Flex Band for $6.99. Because I am an Amazon Prime member I also received 2 day shipping for free. If you’re not a Prime member, you can sign up for a 30 Day Free Trial. On this purchase alone you can save over $10 through Amazon Prime.
