Compatibility: Fitbit Charge 3 and Charge 4.
Material: Metal and leather fitbit band.
Band Length: Fully adjustable to fit any wrist.
So far I find that the band is pretty much what I expected. It looks attractive with my Charge 4 although it is a bit bulky. I found it fairly easy to adjust the size so it fits my wrists better. The one thing that could be improved is the clasp. It is hard to clip together with one hand. I would like to find an attractive band that has a stretchable section so that it could be slipped on and off without having to mess with a clasp. That type of thing used to be common with old wristwatches.
