Let me start by saying that this is a gaming mouse, that is why the cost is pretty high. I've had this mouse for about a year now and can say that I quite enjoy it.
The Razer Copperhead on first glance is quite stylish with it's blue color and unique shape. It actuall comes in 3 different colors to choose from: red, blue and green. With or without the lights on, the Razer's look is dynamic and cool looking.
One of the main reasons for getting this mouse is it's "High Precision laser sensor" that enables you to play at up to 2000dpi. There are also buttons on the side of the mouse that let's you alter the dpi at the push of a button which is nice for quickly changing if the situation comes up.
The grip takes a little while to get used to, but after you are comfortable with it, holding another mouse will just feel wrong and will make you want to quickly get back to that famous Razer grip.
The only problem with this mouse is probably the price, but if you can get over paying a little more, you will definitely enjoy this mouse.
