It worked great. I like to wear an ankle Fitbit when I exercise so it counts my steps on the bike. But I really didn't want any other watch strap. So I just put this extension on and it holds it in place. I also have a Versa 2 face shield for my Fitbit so it doesn't hurt when I wear it on my ankle. I just used an elastic to extend the band around the ankle but it wasn't very strong. It continues to count my steps and measure my heart rate.
