I recently received this mouse as part of a christmas-gift from Razer, and I’ve decided to write a review about. In my opinion most hardware sites don’t have proper mouse-reviews. They either don’t know what they’re talking about, or are afraid they won’t receive any more review samples if they’re too critical. One notable exception is ESReality.
I think I do know what I’m talking about, and I don’t get review samples anyway 😉
You might have read my review of the Razer Barracuda headphone/soundcard combo, if you did, you’ll know I might be a fan of Razer, but not a fanboy.
Keeping with Razer tradition, the Lachesis is named after yet another venomous snake. I’ll start off with some specifications.
Specifications (and what they mean in plain English)
4000DPI 3G laser sensor
This means you can move 4000 pixels on screen with just 1 inch of mouse movement. Razer calls it a ‘3G’ laser sensor, which means you should be able to move this mouse at high speeds without the mousecursor skipping (like the Razer Copperhead 1G laser mouse)
Using the drivers you can save button bindings and macro’s to the memory inside the mouse. When you take the mouse to a PC that doesn’t have the Razer drivers, you can still use the settings in this memory. This way you can use advanced macro’s without the drivers. You’ll only need to drivers to save them to one of the 5 available memory-profiles.
Using two buttons you can change the DPI in 125DPI intervals. This is again possible without drivers (as long as you keep two buttons bound to DPI changing of course).
By default, USB mice report 125 times per second (125Hz). The Lachesis can report 1000 times per second. This will cost you quite a few extra CPU cycles, but will make the mousecursor move smoother. I don’t use 1000Hz, but 500Hz, because I can’t feel the difference between 500 and 1000Hz ingame.
Shape and feel
Besides the specs there is the shape of the mouse. It’s an ambidextrous design, which means both lefties and righties can use it. Compared to the Razer Deathadder it’s a rather small mouse. A lot flatter and less ‘fat’. If you have big hands it might be a bit too small.
The Lachesis has a lot of buttons. 4 on top (5 if you count the scrollwheel), 2 on the left side and 2 on the right side. You can only use either the left-side buttons or the right-side buttons (depending on if you use your left or right hand). Compared to the oversized sidebuttons of the Deathadder the side-buttons on the Lachesis feel small.
The entire mouse is covered in a kind of rubber, the same used on the Deathadder. Like all Razer mice, the buttons are more sensitive comared than you’d expect from a normal mouse. This might take a while to get used to, but in my experience it makes your clicks register slightly quicker.
Scrolling feels exactly the same as on the Deathadder, almost silent and with very good feedback ‘clicks’.
The mousefeet are made of the Razer-standard teflon. Which ensures smooth movement across your mousing surface.
If you use Windows XP and multiple users the following will happen: ( I know it will because I’ve tested three different mice on 2 different PC’s and 2 fresh XP installs)
1. You power on the machine and log in using USER1
2. You leave for work/school/cafe and keep the PC turned on
3. Your friend/girlfriend/brother/parents log in using USER2
4. When you get home you log out USER2 or use ‘fast user switching’ to switch without logging out.
5. Approximately 10-30 minutes later you’ll get a blue screen of death directly after pressing a mouse button.
Besides this annoying bug, the drivers worked perfectly.
Taking it out for a spin
Ingame I bumped the DPI to 4000 and lowered my game-sensitivity to compensate. This way I got the most precision while maintaining my normal mouse-movement-to-ingame-view-turn ratio. I normally use a Deathadder which is a right-handed mouse. The Lachesis being ambidextrous and smaller took a while to get used to. After an hour of fragging I mastered the Lachesis and played as well as with my Deathadder. The mouse is easy to hold, the buttons are easy to push and headshots are almost automatic. A very pleasant experience. However, I did start to experience some annoying quirks. While I was playing as a sniper, I had to lift the mouse off my mousepad (Razer Exactmat) to keep tracking an enemy. When the mouse left the mousepad, my sniper suddenly looked down. Simply every time I lifted the mouse, the view of my brave soldier would shift down a bit. Being a sniper is almost useless like this.
Another problem I found was ‘ghost movement’. Sometimes the mouse just shifts your view up/down/left/right. It only happened once very five minutes, but it also seemed to happen just when I was in combat.
Yet another problem is something I’ll call axis-lockup. This means that sometimes, for whatever reason, the mouse stops responding to all movement on a certain axis. You’ll either only look up/down or left/right. This ‘lockup’ only lasts a second, but is very annoying.
I tried switching mousing surface from my Razer Exactmat to my desk (white with some texture). Ironically this surface worked better than a Razer-brand mousepad. Still, the quirks remained. Today, Razer released a beta firmware aimed at fixing these problems, but unfortunaly it didn’t fix these problems for me.
These sensor problems should have been caught by Quality Control. I experienced these problems within the hour, there’s no way this could/should have slipped by QC.
-Lots of bugs in the current sensor firmware
-Only two of the four sidebuttons are usable
Obviously the Lachesis is a mouse with a lot of potential. Extremely high resolution, movement speed and a good design should make the perfect combination for a great gaming mouse. Unfortunately the bugs in the laser sensor make it impossible to recommend this mouse to anyone right now. Also it’s a rather expensive mouse when you compare it with the Deathadder and Diamondback 3G. Both of those don’t have the sensor bugs and have been around for a while..
So to sum it up. If you’re looking for an ambidextrous gaming mouse, buy a Diamondback 3G. If you’re looking for a right-handed gaming mouse, get a Deathadder. If you want the latest and greatest gaming mouse, wait for a firmware that fixes the bugs in the Lachesis.
To be fair, the Deathadder had some problems when it launched as well. Fortunately a few firmware updates fixed those. Let’s hope the Lachesis gets the same treatment and ends up being just as good as the Deathadder.
