Received this recently and made a big difference! First of all is it fairly large, not as large as some but still perfect for lower sensitivities. It doesn't slip or slide around and is quite a thick material.
I use this with an MX518 and tracks perfectly, the shiny black surface isn't that shiny so doesn't effect performance of the mouse at all. One downside is it doesn't come with its own bag, like some of the other gaming surfaces.
Great value for money and perfect for casual and competitive gamers that don't travel to events regularly.
