5.0 out of 5 stars Only Skipped for 5 seconds - then I opened my eyes, June 23, 2008

By	J. Schlegel "Nifheim" (Redmond Campus) - See all my reviews (REAL NAME)

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.

5.0 out of 5 stars Best mouse ever!, September 26, 2008

By	Dean Swiatek "fps_dean" (MA, USA) - See all my reviews (REAL NAME)

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.

5.0 out of 5 stars Fingertip control, November 30, 2007

By	R. Davis (S.E. Ks. USA) - See all my reviews (REAL NAME)

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.
