Lachesis, one of the three Fates from Greek mythology, also means "bringer of silent death" in Latin, according to Razer. It's also the name of the company's new 4000-dpi gaming mouse, and its myriad customization options will help gamers bring an untimely end to opponents.
The Lachesis features the same black, almost velvety, key surface found on most of the Razer mice and has a soft "Banshee Blue" glow on both the click wheel and rear of the unit. There are two buttons along the left side in thumb-reach: two below the click wheel, and another two on the right side close to where your pinky would be. This is an ambidextrous device, so lefties won't be left out. The only thing we didn't like about the Lachesis was that its buttons were a bit too far apart for our tastes at first, and gaming sessions were a bit uncomfortable. Over the course of a few days, however, our hands adjusted, and we were happy with the way the mouse felt.
The mouse features 32K of onboard memory called Razer Synapse, where profiles and user preferences for the mouse's nine programmable buttons can be stored and updated on the fly. Because your settings and the drivers are stored in the mouse, gamers can easily switch from one notebook to the next. The Lachesis also features Razer's latest 3G laser, which offers an 800-dpi increase over its previous 3200-dpi 2G laser, making the mouse almost 25 percent more sensitive.
Customize Your Settings
Similar to the 3200-dpi Logitech G9, Lachesis users can set, and save, up to five custom dpi levels and quickly switch among them, ideal for when you want a fast response while firing a machine gun but a slower one while using a sniper scope. The Logitech G5 and Sandio 3D Game O2 also offer on-the-fly dpi tweaking, but users can't adjust the exact dpi number. We loved using the mouse in our Painkiller: Overdose and Call of Duty 4 tests, though we found that 4000 dpi offered too much movement for our tastes and was so sensitive that quick movements were dizzying. We preferred fragging in the 3000-dpi to 3200-dpi range. We can't guarantee that you're going to see an increased kill count, but using a widescreen LCD with high resolution will definitely help.
Razer Lachesis Verdict
Though it's unnecessary for casual users, gamers and even digital artists looking for a mouse with customizable sensitivity settings and versatile controls should put the Lachesis at the top of their list. We love that it stores all your settings right on the mouse. It costs the same as the Sandio 3D gaming mouse but offers twice the dpi, and the Sandio mouse doesn't store settings onboard. The only other mouse we've seen with similar options is the Logitech G9, but its sensitivity settings max out at 3200 dpi, and it's priced $20 higher. The Lachesis can't be beat.
