The original Razer Lachesis, which launched in 2007, had a 4000DPI sensor and was one of the few ambidextrous mice that offered left-handers their much needed quality in gaming mouse. Now, three years later, Razer has decided to kick the old pit viper back in action further refining the popular pointer.

The most prominent change in the new Lachesis is the bigger 5600DPI sensor, which puts it together with the other high-end gaming mouses in the market today. The other new addition to the new Lachesis is custom-color lighting. You can now change the color of the scroll wheel and the Razer logo to whichever of the 16 million colors you fancy. It’s not a ground-breaking inclusion, but if you have various light-emitting hardware on your desk, you can be rest assured the old snake won’t stand out like a sore thumb.

The Lachesis is exactly like its predecessor – it has a longer nose than your average mouse, with a high-arched back and pronounced bends on the left-and-right buttons. Coming from the Razer Mamba and Gigabyte 6980, it took me a while to get used to the Lachesis. Though comfortable while holding it, the extra breath made my brain recalibrate the points of contact – the scroll wheel was slightly out of reach now, making me feel as my fingers were inadequate somehow. Now whenever I scroll, I have to swipe my fingers across the DPI adjusters as well which are located just below it. I also found the buttons hard to press, they certainly require more push than the Mamba, but thankfully, I got used to it pretty quickly.

Being an ambidextrous design, the Lachesis features two additional buttons on the right side of the device as well – the two thumb buttons for the lefties. Disappointingly, I found them to be quite useless. The shortcoming is by design itself, somehow giving a feel that they are not meant to be used, not surprising then that Razer have them ‘switched off’ by default (they can be assigned any key or functional through the software, however). The thumb buttons are hard to press, on both sides, which invariably force me to press the buttons on the other side as well due to the force required to make a click. It’s not ideal during gameplay at all, and I had to remap my ‘nade function to a button on the keyboard.

The new Lachesis is a performer like most Razer mice are – it’s comfortable, provides optimum grip and gives precise control over my movements. However, if you already own a Lachesis, there is no reason to upgrade to the new one. The bigger DPI makes no difference over most resolutions anyway; and the customizable LED lights are certainly not worth the $80 price tag. But if you are a lefty yearning for a good quality gaming mice, you seriously cannot go wrong with the Lachesis. For right-handers, there are much better options available at your dispose, some even slightly cheaper as well.
