I love Mionix, I have the Nash 20's and the Naos 7000 which I love love love. But this mouse pad, the Propus 380 is questionable. It seems to do better with laser mice than it does with optical but even then, I have noticed times when there is pointer movement when the mouse or table, nothing, is moving. It seems to me that some refracting or reflecting or something with those shiny bits is messing up the precise tracking of otherwise great mice. I tested no less than 5-6 mice on here ranging from the Naos 7000, the Naos 8200, some generic Dell mouse, a Gamdias mouse, Ttesports 10m, and a Razer Death Adder, so yeah 6 and they all did this to a varying degree.
