I'm curious what everyone's experience has been with aluminum mouse pads? I picked up a mionix ensis 320 (black) a few days ago and while i like it 2 days in there's already a small silver chip in it. I was concerned about how resilient it would be before i bought it but oh well. Has anyone else had one of these pads for a little while, or something similar? How is it holding up? I'm wondering if the silver version would hold up better or just hide the flaws better?
