  Ultra precise, this mouse has a lite feel to it when using, but being a fingertip control mouse that is a good thing. I was used to an older MS intellimouse explorer which is a palm mouse, took a little adjusting, like using a wrist pad for support. But it glides so smoothly that just using your fingertips is easy and feels right.
  
  Like how you can change the cursor’s up and down speed separate from the sideways speed. Setup profiles for each game and the mouse will change to that profile when that game starts.
  
  Has more buttons than I have fingers…6 extra, 2 on each side and 2 right behind the wheel.
  
  Being able to change the speed of the cursor on the fly in game is a great feature…
  
  For the price: The quality is fine, software has every adjustment known to man. Windows Vista Ultimate had no problems installing it. But for the price, I’d expect it to last 3-5 years…of daily use. So at this point after one month, I’d give it two thumbs up.

  I never really thought the mouse made a difference–in fact I was quite satisfied with my Microsoft Trackball–until I got a Copperhead. This time around, without question I bought a Lachesis.
  
  Good refinements in shape here: the head tapers perfectly to make accessing the side buttons easier while providing a good-sized spread for my largish hands to rest on the buttons. Sensitivity can be adjusted with dpi buttons in the middle, which make for a nice touch when you’re on-the-fly switching from an FPS to an MMO, or just going from gun to scope to grappling hook, as I’ve recently done in Lost Planet. Razer mice are a bit pricey, but if you have the means, it’s certainly worth the luxury. Go on–spoil yourself!

  I owned MX1000 from logitech (work/gaming). So i was little bit courious about this piese from Razer. The new replacement came in very good designed box. Easy to install, easy to use. Kind light. Surface is very good choosen, it’s like very soft grip surface, no slides under the fingers. It is more designed for “claw” handling, but the “spider” is as well optionable.
  
  Profiler is full of options (extra for “win” and “games”), speed (even for vertical and horizontal) overall speed, overall DPI. Assigning buttons, macro section. 5profiles, you can save profiles/configs separately.
  
  extra profile switcher under the mouse.
  
  During gaming i have to start on 2000 and after “Warm up” i switch to 4000, rapid “fragging” came instantly. THANKS guys.

  There are few cons, it is very senstive, so any dust/hairs and other small think on mousepad, cause some really weird movemends. My middle finger used to be on mouse whole time. This one forced me to let finger lay on the small piece between the mouse1/mouse2 buttons or on rollbutton (which force me to handle mouse little bit more different, farer), other ergonomics are really excellent.

  I am still learning to game with it, but it is definetely, the most precise mice on market.

  With exactmat it is really uberfragging piece of weapon hardware GAMERS LOVE RAZER

  Always impressed with Razor products. I had the copperhead but moved on up to this mouse. If you like high sensitivity (especially for gaming) there is no other mouse better. one iffy thing is the upper side button. It is a little hard to push but it might just need to be broken in.

  The mouse works excellent. It skipped at first, then I turned it over and saw the clear soft plastic protective cover that covers the bottom of the mouse and partially interupts the laser. I removed it and the silver sticker that goes around the lazer as well and it has performed flawlessly since. Excellent for games and I do CAD with it as well. So if you’re skipping, try uncovering the lazer D.A.

  I’ve been using a Copperhead for a while now. What I liked about the Copperhead was the precision and neutral hand orientation is friendly to us lefties. I thought my Copperhead was dying because I couldn’t get the drivers to work so I ordered the Lachesis as a replacement.

  Logitech has surpassed 2000dpi, but they have yet to offer the same smoothness as the Diamondback not to mention the Copperhead, which completely negates the purpose of 3200DPI.

  This mouse is 4000dpi and offers the same smoothness only at higher resolution.

  I was initially worried that I might have some problems with lift off, and jumpiness. The mouse shipped with firmware 1.64, and I upgraded to 1.75. Neither firmware had a problem.

  The “lift off” movement was no more than 10-20% worse than any other laser mouse which is barely noticeable. Considering the precision, you can’t ask for any better than that – plus with this kind of precision, do you really need to lift the mouse? The days of the ball mice are over!

  The buttons on the side of the mouse are easier to reach than the copperhead as well.

  I’m still getting used to the shape vs the Copperhead, but so far I do not find it any more or less comfortable, I’m just so used to the Copperhead that I’m surprised when I put my hand on something else. My initial reaction is “who cut the sides off my mouse”, but overall the feel is close.

  I use it with an eXactmat and the Lachesis works excellent on both sides.

  The razer lachesis is pleasant a reprieve from the last razer product I purchased (lycosa keyboard). The people on here either bought too nice of a mouse, or don’t know how to read the manual. I am a high end gamer, that plays games at very high resolutions and am very satisfied with my purchase. This mouse is perfect if you have the right surface to use it on. You want a hard surface, preferably a razer mousepad. I have the razer exactmat and I love this mouse. If you have that, this mouse performs beautifully. The only thing that i could see causing a problem is the fact that the mouse is a little big for some people’s hands. The mouse definetly takes some getting used to, but once you calibrate it right, and can fully utilize it, it is amazing. It is by far the best mouse i have ever owned. If you aren’t an idiot and can calibrate the mouse right and accept the learning curve of how to use it, this is the mouse for you.

  Pros:
  
  Excellent smoothness in mouse strokes
  
  Lighting on it is second to none
  
  Many programmable buttons
  
  on the fly sensitivity
  
  Very precise

  Cons:
  
  Too sensitive if you don’t have the sense to calibrate it
  
  Price is very expensive

  Don’t believe all the morons that have reviewed this mouse, look at the review of the razer lycosa that I tore up, and believe me when i say this is a fine piece of equipment. I’m not just a razer “groupie”

  All I can say is this is another great Razer product. It did indeed come right out of the box with all the problems people described in other reviews. I installed the provided disk drivers and restarted as per instructions. My computer restarted and the mouse went dead. I had to unplug and replug to get it to power up. The mouse powered up and mouse movement was extremely jumpy and wouldnt move correctly. Reading reviews and looking around before I purchased the mouse I had a memory jog and was reminded to take the clear plastic off the bottom. PROBLEM SOLVED. I played around with the mouse and found that it would lag a second or two before moving after sitting for a couple seconds. Another quick trip to the review pages and found that this is an easy remedy. DOWNLOAD THE UPDATED DRIVERS! That task completed and the mouse moves and works like a dream. In this day and age with software and hardware upgrades it should be all but instant to go to a website and download the latest driver. I wont insult anyone but if you expect any computer part or product to work right out of the box without updated drivers you’re more than likely sorely mistaken.

  I use this mouse with a steelseries mousepad and they are a great together. I personally love the look and feel ot Razer mice and they are a great fit for my hand and wrist posture. I havent played with any of the marco capabilities or anything like that but if it holds true to with other Razer products I wont be disappointed.

  The only true recommendation I would offer someone that cant be fixed with a trip to the net is a trip to a local best buy or similiar store to see how the fit and feel to your hand will be. If you like what you see and feel hands on you wont be disappointed once you start using it.

  Like mentioned above, dont let some of the down reviews deter you from this mouse. Take the plastic shipping sheet off the bottom and install the updated drivers and you wont be disappointed.

  As far as usage I use this mouse for everything. WOW, COD4, BF2, Dawn of War II, are all on my active gaming list I’ve used this mouse with as well as a little Corel and photoshop’ing. Its meets my expectations and more.

  The thing about ‘gaming’ hardware is that people are very very very picky. When I first decided to buy a mouse with a decent DPI I remember feeling like there was absolutely no choice because EVERY possible mouse had a good share of scaling negative “I’m a pro take it from me” reviews. I’ve owned a Razer Diamondback for about a year, at 1800 dpi. I loved it. It completely changed my online FPS performance (given that I’d been using a cheap wireless mouse before that). I got this Lachesis refurbished for cheap, but now that I’ve used it, if it broke because I stepped on it or something stupid like that I’d definitely spend $60~70 to replace it.

  The buttons on the side: This is an ambidextrous mouse, meaning the buttons on the side are made so that they are easy to press with your thumb, so obviously on the other side of the mouse you don’t have another thumb. Because you can use this as a lefty or a righty, one side of the mouse will have buttons that aren’t exactly natural for your fingers to use. While this may be a ‘con’ the advantages gained in the excellent precision and high DPI greatly out-way this.

  Hardware breaks, period. Especially this kind of hardware. The difference is that when someone breaks their logitech or microsoft or whatever cheapo mouse they don’t immediately go write a negative review about it, whereas if their expensive gaming mouse breaks they get pissed real quick. This is the second Razer I’ve owned and it feels absolutely solid and I have no qualms about its quality. The advantage its given me to online gaming, just from switching from an already impressive older Razer, was evident in the first thirty minutes. Highly recommend, also remember to download the newest firmware.

  This Razer Lachesis is a great mouse, which you can use anywhere on almost any surface (the laser doesn’t work on glass obviously). The 4000 dpi are more than enough, personally too much for me but since you can reduce the dpi easily with the two buttons in the middle no problem at all. I liked the feeling of the mouse a lot and the cool design anyways. I personally think this is a great product and after I tested it out I bought a second one as a gift for my brother! Really nice mouse for gaming and high precision work, but if you don’t do either you probably don’t need this mouse. The driver with which you can program the mouse buttons seperatly works fine and is quite user friendly. Overall a great mouse!
