Excellant product - fits well and is appealing to the eye
I ordered a black Twist-o-Flex band for my Fitbit. It arrived beautifully packaged and looks even better than advertised. I’ve worn Twist-o-Flex watches and have always been happy with how easily they work and how well they hold up. The instructions were easy to follow and I’m happy with my purchase. Customer service was quick to respond to a question I asked. You don’t get that kind of old school service often. Good for you, Speidel!
Like this better the band that comes with Fitbit.
I bought 2 different flex bands for my fitness trackers…luv them! Will not hesitate to make more purchases in the future.
