Nichalos Yaung –
The Black gives the model most of its personality, while the relatively restrained case keeps it from feeling too busy. The listing made this version stand out to me for a couple of reasons. I’ve only had a short time to evaluate it, so I’m keeping my comments focused on the listed design and initial impression. Overall, the configuration makes sense for what I wanted.
