Twist o flex

Fantastic. Love this type band. First had one in military, loved it ever sense.

Great Band

I'm a senior citizen and don't like the watchbands that have to be fastened like a belt. Besides the Speidel band brings back some fond memories of days gone by.

Speidel stretch band for Fitbit.

Absolutely love it.


Wish it was easier to take out or to add back in links in the bracelet. Had to take it to a jeweler twice to get it right. That said, I love the look with my Fitbit.
