Razer Lachesis 30

Razer Lachesis Review

The Package

As with most recent Razer products the Lachesis gaming mouse comes in a black cardboard box. If you open the front of the package you can inspect the mouse for any visible faults. One of the main features of the Lachesis is its 4000 DPI third generation laser sensor that you can read all about on the package.

On the back and side of the package you can read a lot about the features of the Lachesis. Right from its symmetrical design to its state-of-the-art laser sensor. When it comes to specifications the Lachesis seems to be well ahead of its competition both when it comes to shear sensor performance and usable features. The Lachesis has way fewer gimmicks per square inch than the Logitech G9 and the much debated Microsoft Sidewinder mouse.

One of the things that I have always appreciated with the current generation of Razer mice is the bundle. You get everything you need to install and maintain the mouse. As you may already have noticed the Lachesis doesn't feature any form of weight or size adjustment which means that you can't customize the Lachesis as much as, i.e. the Microsoft Sidewinder or Logitech G9. I have owned several mice with weight adjustment kits and the likes. I found that most mice either perform or they don't, the customizable weight systems are just a marketing gimmick. I know some of you probably swear by either a heavy or light mouse, but if you just try using the mouse with the same weight for a while I bet that you will find that the weight of the mouse is irrelevant to a certain degree.

Closer Examination

I think it is safe to say that the new Razer Lachesis doesn't look anything like the other recently reviewed Razer mice. The "Batmobile" looks are accentuated by the rather odd combination of curves and slopes that run along the full length of its body. The basic shape of the Lachesis reminds me a bit of the old Razer Boomslang because it had the same tight back body that curved outwards towards the buttons and scroll wheel. What really sets the Lachesis apart from the other high DPI Razer mice is the fact that it's way wider which should make it more comfortable, at least in theory.

The Lachesis is the newest high DPI mouse from Razer which is clearly aimed at high sensitivity gamers due to its shape and performance specifications. What surprised me a lot was the fact that the new 4000 DPI sensor from Razer can produce coherent tracking even at the speeds in excess of 60 IPS (Inches Per Second). Back in the day when the laser sensors first hit the market the first performance feature to suffer was in fact high speed tracking, in favor of a sensor which had a higher resolution. Now after a couple of years after their initial release we begin to see the first laser sensors able to compete with optical sensors in that part of the performance specter. This is of course a pleasant surprise because it undoubtedly will allow people using a low to medium sensitivity to benefit from laser sensor technology.

The most odd design feature of the Lachesis is by far high palm plate that looks so strange at first glance.

The whole design of the front section of the mouse is pretty similar to what we have seen on the latest generation of Razer performance gaming mice. The scroll wheel is still illuminated with a blue LED and placed dead center along with the rigid cord mount. The only new addition featured on the front of the Razer Lachesis is the arrival of designated DPI up and down buttons which should help to make DPI switching in-game even easier and faster. The buttons are placed a bit closer to your palm than the scroll wheel, but they are still within reach and easily accessible.

The scroll wheel area on the mouse looks quite clean. Razer has opted for a solution where you have a couple of buttons right in front of the scroll wheel (looking at it from your palm). The buttons are usually used to alter the sensitivity or DPI setting of the sensor, but can be reassigned through the driver to pretty much every key you want them to replicate.

If we take a look at the mouse from the side it's pretty evident that Razer has tried to create something radically different from their other mice. What is interesting to note is the fact that the palm plate is raised quite a lot compared to the Diamondback and Copperhead. Since the Lachesis is a symmetrical mouse you get two sets of side buttons. These thumb buttons on either side are quite firm and have a really short travel length. The buttons themselves are really firm and feel durable because they don't give way to pressure like, i.e. buttons on a Microsoft IntelliMouse Explorer 3.0.

When it comes to build quality the Lachesis is no let down either. It's probably one of the best built Razer mice, and everything seems to be very well constructed from a durability point of view.

As with pretty much all available Razer mouse today the Lachesis features a bulky gold plated USB connector. Both the connector and the cord assembly on the mouse are a pretty sturdy construction.

The Lachesis features some of Razer's brilliant soft Teflon feet. They are a bit thicker and a bit softer than what the competition uses. For normal use on a mouse pad the Teflon feet work flawlessly, but take note that they will wear down relatively fast if the mouse is used on a normal hard wood desk and they are quite difficult to replace once worn down due to their strange shape. When you have gone through a pair of Razer mouse feet you are only left with two options: 1. buy a new one, or 2. buy some gaming grade mouse feet Teflon (since nobody produces precut kits for the Lachesis yet).

Another interesting feature that the Razer Lachesis sports is 32 KBs of internal non-volatile memory used for storing profile data. Since the mouse lets you store sensitivity and DPI settings within the mouse you can actually access these settings even when the mouse is plugged into a computer without the proper driver installed. This is a really neat feature if you often format your hard drive or want to use the same mouse with more than one PC.

The most revolutionary feature of this particular mouse is by far its state-of-the-art laser engine. The sensor has the maximum resolution of a whooping 4000 DPI which is 800 DPI more than any of the competing mice in this market segment. Now DPI isn't the only performance aspect of the sensor that Razer has managed to increase with the Lachesis. Also the ability to produce coherent tracking is much improved over last generation laser mice. The Lachesis sensor is said to be able to track movement accurately at 60-100 IPS, which makes it the first laser sensor to be usable for low to medium sensitivity gamers, at least theoretically.

The length and width of the Lachesis is pretty much the same as the DeathAdder and Diamondback. However, the shape and curvature of the shell is radically different. The bulky back end and flat front makes the Lachesis feel unnatural compared to mice like the Microsoft IntelliMouse Explorer 3.0 or the DeathAdder.
