The Aegis series of Armaggeddon mousemats, feature the roughest glide, with the best control. The improved tracking due to the textured surface as well as a constant level of friction, allows for greater control. Highly recommended for FPS gamers. It is recommended to use the Aegis mouesmat, with a mouse that has ceramic mousefeet, as Teflon would be subjected to quick wear and tear. Having a mousemat not only aids performance due to absorption of shocks from friction and bumps, but it also can improve comfort and discourage habits which result in RSIs (Repetitive Strain Injuries).Armaggeddon Mousemats come in 25 different models, differing in Pile (thickness: 1mm, 2mm, 3mm, 5mm), Parameter (size: 13?, 14?, 17?, 23?) and Glide (surface: Speed, Balance, Control). All Aegis mousemats come with a combination these 2 features: ¥Pile refers to the thickness and density of the mousemats. Density is determined by the intended usage, balancing between firmness and shock absorbency. ¥Parameter refers to the size of the mousemat, indicated by diagonal distance from corner to corner.
