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.

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.

Here is my mini review of high end mice I've tried recently.

Razer Lachesis 4000 dpi Laser Gaming Mous--Banshee Blue (4000 DPI, 9 buttons): This is the first mouse that gave me actual pain my my fingers and palm after just a couple of hours use and it has just about the worst ergonomics of any mouse I've ever used. The side buttons are in a very inconvinient location. In first person shooters you'll constantly be accidentally clicking either side's buttons since they're in the area where you grip the mouse (they're designed so you need to put "extra" pressure in the grip to click them). The laser itself is pretty decent at 4000 DPI, but it is placed in the middle of the mouse instead of closer to the front, so you basically need to move the whole mouse to aim instead of the regular first person shooter "tilting the front of the mouse" aiming. Be sure to go to their web site and use the updated drivers and firmware or you'll see a lot of "mouse jumping" problems even when you're not touching the mouse. Also I noticed the mouse buttons would register as "up" as I was turning sometimes with the mouse button down (such as a Heavy in TF2 spinning his gun using the side button, which is annoying as heck). There is also no on-mouse DPI display so there's no way to know which DPI setting you're at (one of the five DPI settings you're forced into). Anyone had any good experience with this mouse?

Logitech G9 Laser Mouse (3200 DPI, 7 buttons, weights, two grip types): I used this mouse for a bit less than a year and it is by far my favorite mouse.
