Razer Lachesis 5,600dpi Review
The Razer Lachesis gaming mouse originally launched in 2007, with a dramatically curved, ambidextrous design and a 4,000dpi sensor. Three years later, Razer has released a new Lachesis, which is not so much a sequel as a refinement of the original.
The most important change in Lachesis 2.0 is the 5,600dpi sensor, which puts it on par with other top-end gaming mice. We don’t usually play at such a high sensitivity, but we tested it at dpi levels across the whole spectrum and found the Lachesis responsive and reliable.
The other new addition to the Lachesis is custom-color lighting. That means that (after downloading the Lachesis driver) you can change the color of the glowing scroll wheel and Razer logo to whichever of the 16 million possible shades you fancy most. Earth-shattering? Not exactly, but it is nice that you can match your mouse’s glow to your keyboard or any lights your various hardware might emit.
The Lachesis v2 may look the same as its predecessor, but it sports an improved sensor and customizable LEDs.
The Lachesis form factor hasn’t changed, but that’s all right—it’s still an amazingly ergonomic mouse. It’s bigger than your average Razer mouse, with a high-arched back and pronounced grooves on the buttons that make it a very comfortable fit for anyone with medium-to-large hands.
The right and left mouse buttons feature a solid clicking mechanism, and the mouse has two extra buttons on each side, though the buttons on the off-thumb side cannot easily be pressed without moving your hand. On top are two more buttons behind the scroll wheel, which has a tight, clicky feel, though it lacks sideways tilt functionality.
The standard raft of gaming features are all here, as well, including on-the-fly adjustable sensitivity and multiple user profiles. Nothing too exciting here.
And that’s really what you’re getting with the Lachesis: a dependable gaming mouse with a time-tested form factor, a high-caliber sensor, and solid software support. Nothing innovative, but a solid buy for the money—especially for lefties and those with size-XL hands.
RAZER LACHESIS 5,600DPI

REDUX
Excellent, ergonomic build for people with larger hands; great sensor; ambidextrous design.
REHASH
Only two side buttons are really accessible; not great for people with small hands.

The Razer Lachesis has been around some time now but a new version has just been released with upgraded sensors from the original 4000 to a new 5600 dpi Razer Precision 3.5G laser. Its lighting system has also been upgraded, with customisable lighting feature you can now change the colour of your Lachesis 70-548 to any of 16 million different colours thanks to the installation of a multi-colour LED into the chassis.

Sounds like a nice mouse. Too bad the company doesn't have a KB that has more than one color option. I've heard theirs are nice but since they all come with a single LED color standard(blue *ick*) I'll not be buying their peripherals any time soon. My G9x is weighted, 5700 dpi capable has as many color options and since I'm right handed(really the only plus in comparison) the perfect choice for my gaming needs.
I'd be open to purchasing one of their KBs' if it had more than one color option. My system only sports Red. I sleep in the same room and when I wake up in the middle of the night I'm not blinded by my system. I even pulled and replaced the LEDs'(3mm low intensity bulbs) in my HAF 932 because they were lazer bright.
Back on topic, the ambidexterous use of the mouse is a nice option however. I've found myself at the mercy of desk space and while my mouse is pretty easy to get by for the short term with, if I had to Translate hard copy to disc, it would be much nicer to have the ability to slide the mouse to the Left side of the desk and stand the hard copy on the right side of my Keyboard. I'm right dominant if you cannot tell already. lol

Actually it's rare for a publication to list price on anything. They'll list Suggested Retail, but I'm sure even that gets readers in a frenzy. Something along the lines of this:
"You listed blah blah Graphics card in the December blah blah issue and stated that it was $100. But I went looking for it and nobody had it for less than $1 million. What gives!!!! A pox on thee!!!"
In the current issue there was a Home Media Server build that had prices but those were the prices at time of purchase. I don't think anyone has a problem with this. Though I found a reasonable AMD setup(it was Intel based) for a bit cheaper and allowed me to tinker with better components and still be cheaper. Not a fanboi just realize that there are people that are pigeon holed into a budget. lol

Perhaps it's one of those deals where if you have to ask how much it costs you can't afford it.

Looks nice... I do have a question, how much of an impact would a wired mouse such as this one have on battery life on a laptop or netbook?

I use my G9x with my Netbook and it really doesn't use that much power. It's pretty negligible actually.
