5.0 out of 5 stars Great gaming product. REMOVE PLASTIC FILM FROM THE BOTTOM AND UPDATE YOUR DRIVERS BEFORE JUDGING!, May 7, 2009

This review is from: Razer Lachesis 4000 dpi Laser Gaming Mouse (Banshee Blue) (Personal Computers)

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.

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

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 2nd Razer I've Owned, Exceeded Expectations, May 23, 2009

This review is from: Razer Lachesis 4000 dpi Laser Gaming Mouse (Banshee Blue) (Personal Computers)

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.
