I received my new band within a few days and love it. It fits perfect.I ordered from Kate in order department. She was wonderful. I will order again soon. Sherry A.
The band was a gift and he loved it!!
Great quality, ordering was easy, and delivery was fast.
I've been a watch guy for a long time. Now the FitBit Charge 3 fills the roll with fit and function. I was apprehensive about a flex band because I had been burned in the past. After doing my research I chose the Speidel and was more than happy with the performance. I have fairly hairy arms and it does not tug at my hair or pinch my skin. It seems the band is aging at the same pace as the FitBit so the band looks like it is in it for the long run. I am jazzed about my purchase.
I love the new band I purchased for my new Fitbit.
This band is great. Easy to put on and no more catching on clothing.
