Takes my Fitbit Charge 3 to the next level

Love the convenience of this Speidel Twist-O-Flex.

charge 3 band.

Very satisfied. do you have any other designs for the same watch other than black or silver?

Great Product.

Have been using Twist o flex watch bands for the last 50 years or so.

Very nice looking

It was a little pricey, but well made and comfortable.

Just the ticket for a fitbit

Perfect fit from sizing chart. It's a great improvement over the band that came with the Charge 3. Looks dressy.
Ordered another for my wife. Her original getting dingy, I'm sure they'll last for some time to come. An elegant case and cleaning cloth was a nice touch. . Thank you.
