I4U News take a further look at the Razer Lachesis laser gaming mouse. Here's a taster:

In use, the 4000 dpi is great for me since I prefer high sensitivity. The Razer Lachesis is very accurate and tracking is great. I used the Lachesis for playing lots of Crysis. The high-sensitivity settings were perfect for fast turns and the mouse was very accurate from close range and long distances. Tracking fast moving targets was a snap and the adjustable sensitivity was welcome.

The Lachesis is good for things other than gaming too. I very much like how little hand movement it takes to navigate around my 30-inch display and around web pages with the mouse. When I use Photoshop the accuracy allows me to pick specific points for cropping images with ease. The layout of the buttons is very good for the most part. The way I prefer to grip a mouse puts the buttons on the right side out of comfortable reach.

The buttons on the left side of the mouse fall exactly where my thumb typically rests when I game. Normally when that happens they end up being clicked accidentally. However, the buttons on the Lachesis require more than an accidental touch to activate them. You have to want to use those buttons, which is a good thing. When you do want to activate the side buttons they are easy to click and offer good tactile feedback.

The Razer drivers allow you to turn the lights behind the scroll wheel and the Razer logo on or off as you desire. The drivers are very good, as is typical for Razer. You can map different profiles inside the drivers for specific games. 32KB of onboard memory allows the mouse to store the profiles for use on computers without software installed. A button on the bottom of the Lachesis allows you to change the profile to your preference.
