Also note for anybody buying these 2...
When sticking the icemats sticky feet to the bottom of this mouse dont apply them to the actualy feet pads already on the mouse, it doesnt level out and it mouse wobbles, stick them on between the feet pads and its perfectly level and glides smoothly over the mat.
Also makes this mouse so precise !
Was using a gell cloth top mat for the last 3 years and the change over i noticed so much differnce between them.
