Rating: - Nice mouse, but worth it?
I purchased this mouse specifically for gaming. I am not a hardcore gamer, I just play on the days that my busy schedule allows. I would like to say it helps out me game considerably, but I am not able to say that. I have only owned this mouse for a month, and maybe I just haven't got the buttons down yet.
The appeal of this mouse was the extra buttons that could be programmed. The mouse I was using only had two programmable buttons, and he though of all the extra buttons that would allow ... Read More
Rating: - 2nd Razer I've Owned, Exceeded Expectations
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 got this Lachesis refurbished ... Read More
Rating: - Nice but very sensitive!

Rating: - Great gaming product.REMOVE PLASTIC FILM FROM THE BOTTOM AND UPDATE YOUR DRIVERS BEFORE JUDGING!

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 ...

Rating: - Not Impressed ....
I am and have been a Razer gaming mouse fan for several years.I have owned a few Diamond Backs and have been very pleased with their reliability and accuracy ... so I thought the Lachesis would be an upgrade to my Diamond Back.

This mouse did have great speed and adjustability on the fly, but there were more negative features than positive.I found that the side buttons were way too stiff to push, especially the side opposite my thumb, the ergonomics was not a good fit for my hand, and worst ... Read More
