the old death adder is good...mine lasted me 4 years...then i replace with another new death adder...heck it fails me after 2years...but i do plan to get the new death adder 2013...i have to admit the quality on death adder is dropping..as i compare with my new deathadder with the old ones...i can see a lot of different such as the scroll has a huge gap which cause the scroll to be shaky...and the feel of the new ones is not as solid as the older model..
