Razer has just reached a new height in terms of tracking resolution for gaming mice: its new model, the Lachesis, features a jaw-dropping 4,000 dpi of resolution. It also has an ambidextrous design, a rubber-coated large body and a pulsing blue light Razer logo. As with all the products from the company, the impeccable presentation goes along with the desire of making the best weapon of the virtual warrior. Let’s take a detailed look about the mouse and then proceed to see how the Lachesis fared in the field test.

At first glance, the mouse has an unusual design. Instead of having a narrow head like the also ambidextrous NZXT Avatar (which we already tested), the Lachesis has a Y-shaped head alongside a broad backside. If it were a person, the mouse would take two seats in a bus. The head is also so broad that a small handed person can fit three fingers on top of it. The large and a bit elevated backside delivers a different grip from regular gaming mice (this is either good or bad depending on personal taste and hand size).

The Lachesis has buttons on both sides since it has an ambidextrous design. Unlike the Avatar which features a single button sticking out on each side, the Lachesis has two shallow buttons on each lateral. Being smaller and surface-deep, the buttons above the pinkie (either in a right or left-handed grip) cannot be pressed so easily. The glossy plastic mouse body doesn’t feature finger rests for the toe and pinkie like other designs.

On the top we can find the usual buttons to change the mouse’s tracking resolution and the transparent scroll wheel. It can be lit with a glowing blue light the same as the Razer logo on the broad backside (this feature can be disabled through software). On the underside the Lachesis features a button to change the user profiles (the mouse has an internal memory of 32 KB to save up to five different profiles), three white Teflon feet to ensure a smooth slide, and finally the 4,000 dpi laser cannon.
