I have been using it for a year. It moves very little during sudden mouse movements. Its positives are that it has the right thickness (neither too little nor too much) which helps with comfort and shows quite a bit of quality.

Its size is as stated and it fits very well in a limited office space. The materials look very good on both surfaces, with stability on one and excellent scrolling on the other. I cannot judge its durability yet, but the layers of materials appear well bonded. Excellent value for money.
