SteelSeries QcK Heavy is a monster among desktop cloth pads. Nothing less. It is a super-sized mouse pad made of a high quality cloth material with a specially designed non-slip rubber base which prevents the pad from sliding; no matter what surface the mouse pad is placed on. Its important to notice the difference between SteelSeries QcK Heavy and all other mouse pads from our SteelSeries product line. This mouse pad features extremely heavy thickness which results in a very unique feeling. While the mouse pad is much more soft and comfortable to the touch the height is also fairly massive reaching a total of 6 mm (023 in). Other mouse pads from SteelSeries are very thin aiming to provide a high quality gaming surface as close as possible to the level of the tabletop its used on.
