Have ordered the pad, because I had once bought for my mother one with focus on: black, small, light, simple, good surface ... and have found that the part very thin, non-slip, very very precisely (Laser mouse) and easy is extremely space-saving. The size ranges for everything from safe even for the most games - I'm rather fine motor skills. Since then, I use privately and for the job always one of those, because you can also combine the pad and always carry in your laptop bag. Processing: Irrespective really well handled by the low price, it solves nothing, the pad can be normally purified water, for example if someone spilled coffee next to your calculator). Allow to dry, use it again. ~> Top Pad, cheap, durable, available in several sizes.
