Love being able to take off watch faster!
no more messing with the buckles putting the fitbit on or taking it off, great quality band and end clips. Worth every penny.
So comfortable and easy to wear without any hooks or clasps. I ordered slightly too big, but just push it up and it's working out fine. I really love the stretch. the ease of wear, and looks really good on! I'm very happy I got it, great product!
This band is wonderful. I wish I had purchased it a long time ago. It looks so much better than the rubber band that came with my fitbit.
