Update 07/07/2020: I noticed that the clasp on the black bands has started to break off. Doesn't affect functionality, but only noticeably. My original Fitbit bands don't. Also, the top band will begin to detach from the tracker. I only put it together when I think about it, so it doesn't really matter to me. I have posted two photos showing both. First review: The packaging was nice and easy to open. These straps are small and the same size as the original Fitbit straps. They share the same branding, and you can see in the third image that the slate gray is exactly the same as the original slate blue that came with the special rose gold version of the Fitbit Charge 3. I have black on my fitbit in the last picture. It fits perfectly, fits flush and feels secure. It looks great with the rose gold Fitbit strap. Both of my original straps (small and large) broke when my husband tried them on and the other broke while using them on a bike ride. The small strap was on my Fitbit for 13 months before it broke and the large strap was on for 2 months before it broke. Hope these hold up better. I will update the quality and durability of these.
