Although this is a very comfortable strap, the color fades fairly quickly. I bought this for my Fitbit 3. I don't know if it was a Fitbit or a band, but my Fitbit started working about three months after I started using this band. I've often wondered if the magnet on the strap that attaches to the back of the Fitbit is driving the screen crazy. I'm not saying it was, but I often wonder because magnets and computers just aren't compatible. I don't think the magnet was strong enough to play around with the Fitbit, but I would tread carefully and always lay the strap and Fitbit flat when I take them off so the magnet doesn't touch the back of the Fitbit. .
