Summary: I've had this mouse for several months now. I bought it because it does feel nice in the hand, and the customizable color pairs nicely with my Logitech G510 Keyboard. BUT it has problems. It collects dust around the sensor quite easily, so the cursor will start to jump around until you wipe it off. So if you're trying to game with this mouse, make sure to clean it before loading up your game. Also, I've fallen victim to the poor drivers.
Major Case of 'Fashion over Function' Lefty's give this a pass.

Summary: This is my third Razer mouse purchase. The first was the left-handed Deathadder, then I bought the little Orochi for my laptop bag, and now I have purchased the Razer Lachesis. Each mouse I have purchased from Razer has had its own set of issues. The Deathadder would lose connection with the buttons (laser still worked) when you plug in any USB device, the Orochi was quite unpleasant to use with Bluetooth and now the Lachesis...
Summary: I've had an original Lachesis for a number of years and it served me pretty well - after a few firmware and driver upgrades, that is. This current mouse seems no different - on Windows 7 Ultimate 64-bit the mouse cursor simply stops dead in its tracks once every few hours or so. Thankfully, unplugging the mouse will fix it, but there's absolutely no reason for this terrible behavior.
Summary: First off, let me say that I really liked this mouse but it just wasn't for me (I used it solidly for a couple of weeks). Coming from a Logitech G5, my hand has changed over the last 4 years and I was looking for a mouse that would accommodate a claw/fingertip grip. I've listed the pros and cons below, but the bottom line is that it's too expensive and too particular a mouse.
Summary: 2 stars are because, when it actually worked, it was a great mouse. Reminded me quite a bit of my old Copperhead from years ago. Unfortunately, mine had a very serious fault in that it would completely freeze up with no way to fix it except unplugging & plugging it back in, obviously not very useful while in the middle of a game.
Excerpt: The mouse itself feels good, and the buttons all operate effectively and really feel appropriate. The wheel moves effectively and I only have difficulty finding to the farthest side button on my pinky finger side.The lighting feature is fairly cool - you can set a diverse color for the logo and scroll wheel, and have different colors for distinct profiles (although profiles take so extended to switch, I in all probability won't use them very substantially).
Excerpt: - hassle-free buttons for switching dpi- decent software for customizing buttons- up to 4000 dpi (if you'll ever need to have that)- looks excellent - will randomly lock up and only be able to move left and right, not up and down (this is specially annoying when gaming). takes place pretty much every single day- drivers gave my comp the blue screen of death i rly only purchased this mouse since i saw it on sale for half value and the specs seemed great for the price tag.
Summary: If you're after a good gaming mouse, first thing I would suggest is have a really good look around if you're gonna spend this kinda money. I managed to get this one on offer for just short of £30 and for that price I was pleased. But if you can't get it for alot less than the rrp there are definitely better options. Those with small hands beware, while I wouldn't describe the Lachesis as a big mouse it is quite long.
