Q: How adhesive is the back surface of the Razer Sphex?

A: By design, the adhesive surface on the Razer Sphex adheres to most common table top surfaces made from wood, plastic, glass, stone (such as marble) and even metal surfaces. The surface also retains its adhesive qualities over multiple uses. We however do not recommend the use of the Razer Sphex upon a fabric material as the adhesive would pick-up loose fibers. This may affect both the quality of adhesion as well as possibly create imperfections beneath the planar surface used for gaming.

Q:  Is the Razer Sphex flexible enough to roll up for storage?

A:  The Razer Sphex should not be rolled up for storage and should be kept as flat as possible. This is to preserve the quality of the gaming-grade surface texture and ensure that the bottom surface retains its adhesive qualities.

Q:  Is the surface of the Razer Sphex smoother than the Razer ExactMat X Speed?

A:  In terms of surface-roughness, it is neither as smooth as the eXactMat Speed nor as rough as the eXactMat Control. The surface texture is clearly visible but does not have the graininess of the eXactMat Control. On a scale of 1 to 10, with the eXactMat Speed rated at 1 and the eXactMat Control rated at 10 in terms of surface roughness, the Razer Sphex is rated at 3.
