It's hard to find an all black strap for my Fitbit ALTA HR. I wear it on the same wrist as a black strap watch. It has a gray color around the holes but it's not too noticeable. I've only had it for about a week but so far so good. For some reason the design I'm guessing has 3 sets of holes staggered across the strip. I suspect the outer ones are for decoration and the inner ones for customization. One of the outer openings is easy to slip into by slipping it on, but there's nothing wrong with that. My old band fell off twice when I hit it so I kept it as a spare and will give this one my final judgment when I see how long it lasts.
