Near Endless Use 
2008-10-06
I've had this mouse for over 2 1/2 years and it finally gave me a reason to go out and buy another one, and the new is going to be the exact same mouse because this thing has been so reliable, so precise, and so quick for me.
The middle mouse button appears to have sunk into mouse or has fallen off it's track so I'm gonna be forced to order another one.
Either way, I've never used a better mouse, who needs wireless anyway? This is perfect for gaming and casual computer use.
Damn nifty.

When my MX1000's charger crapped out, I found myself in the market for a new mouse. Based on reviews I decided to give the Razer a try.
The ergonomics of the mouse are nothing special; the shape is just your classical old-school mouse, and the weight is just a little lighter than I'd like. Since I had been used to using the MX1000, which is pretty much the perfect mouse ergonomically, I had a little adjusting to make. It's a pretty-looking mouse though, with a pulsing blue glow... not that you'll ever be looking at it while using it, but its there. There are two buttons on each side, presumably to give parity to the left-handed audience, as the right-side buttons are all but unreachable for right-handers. The side buttons that I do use feel a little stiff, and I have to compensate by squeezing my ring finger a little to keep the mouse stable when I use them, which would be problematic if I ever used them in games (I don't).
You will immediately notice, however, the great sensitivity and accuracy of the mouse, which is its selling feature... and it delivers on this well. At first it takes a little adjusting on the user's part, but now that I've been using it for a while for surfing the web, playing games etc., I can't imagine going back.
The software leaves a bit to be desired though, installation/uninstallation of drivers can require manual registry editing, which seems a bit clumsy. For some reason my mouse is totally disabled by the newer drivers, so I have to use only those bundled on the CD. Also the mouse can take up to 30 seconds to "wake up" coming out of standby, but otherwise there are no technical issues to speak of.
Overall I'm happy with the purchase and have no difficulty recommending this mouse to more advanced users with specific needs for higher sensitivity and accuracy (mainly gamers). For more basic uses though, you would probably be fine with some cheapo from Microsoft.
Wrong Mouse

I ordered the copperhead and received the diamondback. A good mouse but not the one i wanted. I didnt return it cause i needed a good mouse in a hurry and i figured it could take another two weeks to get the copperhead.

Definitely improved my skills in Rainbow Six Vegas 2 when compared to my USB optical mouse. It wasn't a miraculous quantum leap but it was a definite improvement. My shooting accuracy went from around 20-25% (no, I wasn't real good at Vegas 2 to begin with) with the USB mouse up to around 30-35% on average with the Razer. Also, it takes some tweaking of the settings and a few gaming sessions of test driving to get the mouse just right for you.
I didn't give it 5 stars because I don't totally like the ergonomics of the mouse as much as just a plain old regular Dell or HP standard mouse. The Razer feels too long and low for my hands. Also the right side buttons aren't positioned very well (they're used for changing the sensitivity in-game). Also, $50 isn't exactly a bargain for such a simple device.
Overall, I'm happy with the mouse. Like I said, I became a better, more accurate player(about a 20-30% improvement in my accuracy) in Vegas 2. However, don't expect this mouse to perform miracles.
average mouse, get the logitech g5 instead!

So I just built my new gaming rig adn got it with this mouse, it's definetly a nice mouse, good feel, good speed, but my brother came home from college with his logitech g5, so i tried it out. I am now the official owner of a logitech g5 and it was a better mouse. The G5 has interchangable weights so you can have the weight you wish for gaming or what not, The g5 is also a bigger mouse so you get a better feel and a better grip on the mouse. So if you can grab yourself the G5 rather than any razer.

Good, Bad, and Indifferent 2008-06-09
I was really excited to have the Copperhead, and when I first installed the software, that blue glow hypnotized me. What's more, I could see the performance gain instantly--some games I have to turn down the polling rate so I don't sprint circles around the competition. It's even really great for steadiness, working in Photoshop and such: just quickly tap the dpi buttons to get what you want.
Unfortunately, the infrastructure surrounding the Copperhead is not so forgiving. Updating drivers is a bit of a nuisance and prone to bugs. Firmware updates became nigh impossible until I looked in various forums and found tons of users with the exact same problem. After some agonizing "burden of proof" with tech support, they sent me a new Copperhead. I have no idea why hardware would suddenly fail so critically: I've had bad firmware updates that just need to be re-run--they don't brick the unit. But when this happened, I was hosed without a replacement.
I won't buy one again. I'll enjoy what I have. And given the Vista headaches I'm now having with my Lachesis, I don't think the software problems are going to get better for the Copperhead: Razer's probably on to bigger and better things.
Just a warning for people with big hands 2008-04-24
This isn't a bad mouse and the other reviews are accurate for sensitivty, etc
The only real drawback: this thing is tiny
If you have big man hands; you may experience hand cramps trying to hold this thing. I experience pain just trying to curl my fingers in a way that lets me even reach the buttons on the side (they are "under" the side edge and tucked inwards)
If you have little girly hands; than this is a fine gaming mouse
For me; I'm sticking with the logitech series of game mice; they are far more ergonomic for large hand sizes
If you decide you really want a razer branded mouse; try one of the other razer series, some of them are at least medium size (like the lachesis); but the copperheads are the smallest mice I've ever tried (and we have dozens of various gaming mice at my job)
Razaer Copperhead 2008-04-06
The Razer design and construction is quite nice, and the options for controlling DPI, sensitivity, etc via the bundled softare are excellent. Overall its a great product. I gave it four stars because its not quite as comfortable as the mouse it replaced (MS w'less Laser 6000). However, this a gaming mouse that is still pretty comfortable, looks great and works a treat. I am more than happy with the purchase.
Amazing Mouse 2008-04-06
I simply love this mouse. It has everything i could ever want in a mouse for a fair price. Everything works properly and the software was easy to install. I do have a couple complaints. The two left-click and right-click buttons are very long. Im still kinda adjusting now and then for comfort. And the two side buttons on the right hand side are nearly impossible to use, although i do believe they are for left handers. However these are minor complaints that make no difference in the long run. This is the fastest mouse i have ever own. Its just simply amazing and the Teflon feet help make it glide across your desk/mousepad. A feature i found kind of useless is the built-in memory. Im the only one using this mouse so saving different settings like DPI is well....useless :(. And last but not least, the glow! Its pretty birght, and when i turn the lights off its like a bright blue alien light. I know thats kinda silly but this mouse is just that awesome!
