The twist o flex band is still the best band for any application. The quality, fit and finish are first rate. This band is on my Fitbit charge 3. I will be ordering more bands for my good watches.

Twist O Flex band for Fitbit Charge 3

I had ordered a Twist O Flex for my Fitbit Alta so when I upgraded to the Fitbit Charge 3 I ordered a Twist O Flex for it. The band fits well, east to attach to the Fitbit Charge 3. I give a 5 Star and I have recommended to my friends!

Exactly what I needed

I gave my 89 year old mother a Fitbit to encourage her to keep moving. Unfortunately, her fingers could no longer buckle the bank and other options I tried didn’t work either. She really wanted something she could just slip on. I tried several times to find something appropriate but the last time I ran a search Speidel popped up! I remembered the old Twist-o-Flex commercials and thought why not give it a try. So I ordered a small and a medium. I kept the medium for myself and sent Mom the small - perfect! They look sleek and much more professional for me than Fitbit’s plastic bands. And my Mom loves hers, too. I only wish I’d found them earlier!

Fabulous Band

Great service. Band is perfect and easy to put on fitbit. Works like a charm.

Beautiful and Perfect

I ordered XS and it fits perfectly. It makes my Fitbit look sleek and interesting. I matched the black with the rose gold Fitbit Charge 3. I love it.
