Razer has released several very popular mice in the past and the Viper or Diamondback has become very popular. We have a closer check on the new Copperhead mouse from them that is the latest that they have released. This looks like a upgrade from the previous versions and it will be interesting to see if they have actually listened to the consumers and made some changes. We will be testing this mouse during normal use and during gaming so stay tuned for this review.
