Twist-O-Flex Band for the Fitbit Alta and Alta HR

Love the fitbit band from speidel

This is the best looking and best fitting band you can get for your fitbit. It is adjustable to your exact comfort level.

Great Product and Service!

I ordered a Twist-o-flex band for my Fitbit after trying many others without success. The quality of the band is truly amazing and feels like something that would be on a very high-end watch. I did have a problem with adjusting the size to remove some links (the parts are tiny), but when I called customer service to get advice I was offered a replacement that will be sized for me already. The person that I talked to was very nice and helpful. This has been a great experience and I highly recommend Speidel!

Beautiful packaging, impeccable service

Great product. Quality workmanship. Love it.

Comfortable, quick and easy

Much prefer these to the Alta bands that buckle or snap. Removing links to shorten is a major challenge, but possible. Try to order small enough.
