Brondan Green –
I kept coming back to this model when I compared the available options. I like the combination of the Black and bracelet or strap material; it keeps the appearance consistent from case to bracelet. The item arrived in good condition, and the first look matched the listed configuration. Nothing about the configuration feels out of place.
