The Mechanical Keyboard is faster, better and lasts much longer
A mechanical keyboard is already fundamentally different in construction than conventional keyboards as you know them from the office. Each key of a mechanical keyboard has a separate mechanism to feel the keystroke and transmit it to your computer. These are built for higher speed with shortened input path, the standard are the classic CherryMX with 2mm but SteelSeries has now even managed 0.4mm. As a result, the button no longer has to be pressed down completely, which saves your power and time. Especially helpful for enduring gamers because fatigue in the wrist occurs less often.
The advantages of a mechanical keyboard are that the keys react faster and more precisely and the longer durability due to the special design (50 million clicks are guaranteed by default).
