My strap has finally snapped on my 2 year old Fitbit Charge 3 which I wear 24/7. I took a risk by choosing this very cheap group. It snaps into place just like the original and the gray is exactly the same color. Size and fit are very similar. If you've never removed a strap, be prepared for a lot of dust in the buckles! I had to use a toothpick and an old toothbrush to clean it in order to attach the new tape.
