Mouse Razer Lachesis Gaming originally released in 2007, with a large curvature, ambidextrous design and a 4.000 dpi sensor.
Three years later, launching a new Razer Lachesis. Not so much as a sequel if not ato improve the original.
The most important is the Lachesis 2.0 5.600 dpi sensor, which puts the level of other mice with a reputation for computer games.
Usually I do not play with such sensitivity (5,600 dpi). But in testing response spectrum THROUGH found the Lachesis very responsive and reliable.
Another new addition to the Lachesis is that you can personalize the color of light. That means that (previously lower Lachesis driver) can change the color of the glow of the scroll wheel and Razer logo to any of the 16 million possibilities.
The shape of the Lachesis does not change but that is good because it is an amazing mouseErgonomic ement. Is larger than the average Razer mouse with a sharp bend in the back and pronounced grooves on the buttons makes it very comfortable for anyone with a coat of medium to large size.
left and right buttons have a solid click mechanism, and the mouse has 2 extra buttons on either side to press the button but you have left on the opposite side of the big toe need to raise a little hand.
