Massive Multiplayer online games: MMO-gaming is extremely popular and demands specific requirements for your gaming hardware. At games such as League of Legends, World of Warcraft, The Elder Scrolls Online and Diablo 3, a lot of key combinations and commands are given. To ensure your victory it is important to have easy access to all of these commands. The GXT 166 MMO mouse gives access to more than 12 programmable buttons directly at your thumb, so you can quickly perform the required combinations leading you to the victory.

18 Programmable Buttons

Next to the 12 programmable buttons at your thumb, there are 6 (standard) buttons at easy accessible places. This results in an enormous advantage over gamers who are only using a keyboard for complex commands. Instead of looking for the right key combination on your keyboard you can easily perform any command with the mouse without even looking at it. The buttons at thumb panel on the side of the mouse are placed in slightly different angles, making sure you can find the right buttons intuitively.


The sophisticated, well-designed gaming mouse features an ergonomic design, convenient placement of the buttons and the rubber sides provide a perfect grip while gaming. Additionally, the mouse features a LED backlighting which can be easily adjusted to any color you like using the included software. The nylon braided cable easily slides over your table and withstands intensive use.

16400 DPI Laser and Switchable DPI Settings

The extremely precise laser sensor in the mouse works on virtually any surface. In addition to that, with the DPI button you can easily switch the DPI settings between five different profiles for any situation while gaming. Furthermore, you can personalise these profiles with the included software.

Advanced Software

Next to the GXT166 MMO mouse, advanced software is included for personalising the gaming mouse fully to your desires. Saving your personal profiles on the internal memory allows you to play on any pc with your own settings, which is perfect for LAN-parties. On top of that, you can program successive key combinations with the advanced macro manager. For even lower response times, you can overclock the speed of your USB port (1000hz poling rate). At the Trust website, you can read more about customisation possibilities. For example, you can have access to steadily updated customised gaming-profiles with the perfect button configurations for popular MMO-Games such as League of legends, World of Warcraft and The Elder Scrolls Online.
