"Somebody fed this mouse DECON!!!"
However, I'm going to call a spade 'a spade' and just get right to it: the Razer Copperhead is a clean lined, well lighted piece of junk.

I bought the mouse about eight months ago, for a new gaming / media system that I was in the process of building. I got transfered out-of-state for a temporary (6 mos.) job assignment and the whole PC project got put on hold. When I returned, I completed the new system build (complete with a new install of XP (Pro) Media Center Edition). I installed my Panda 2006 Security & Antivirus and Office Pro 2003. I then spent two (2) full days doing broadband updates at Panda, Windows Update, & Office Update. The new system ran like a precision clock, no hint of a fault anywhere. Standard corded (PS2) mouse and wireless USB lazer mouse both performed flawlessly.

So now I remember that slick, new Copperhead sitting across the room on a bookcase shelf. I retrieve it, read all the install data, and install in on my new machine without any problems whatsoever. It ran beautifully as a standard, corded mouse for about sixteen (16) hours that day. I didn't try setting up any buttons and didn't have any games installed on the system yet...but, it still seemed to work great (in Profile 4, the only setting I chose) as a standard use mouse. During this first day, I had shut-down & restarted my new system four or five times without any system or Razer issues. The next day, however, the mouse only lights up (but no lazer emission on the bottom side) and the mouse cursor stays stationary at the center of the LCD display; it will not move. This mouse is dead at all USB ports; my old mice still work fine, everywhere. I've tried the uninstall-reinstall several times and of course went to that FANTASTIC :( support page at the Razer website to get the latest drivers & firmware, but it turns out that my driver CD already had the most up to date versions of both. No luck.

I can't risk fouling up this pristine PC and operating system install for the sake of prooving that this BOZO product is worth a third of the $62 asking price. Maybe I'll just use my standard cordless lazer mouse to avoid system risk and then try to figure out how to convert this Copperhead into a bathroom night light (for the Tidy Bowl Man).

"Good, Bad, and Indifferent"
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"
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"
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"
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!
