Not long after the first Deathadder launched, there was discussion amongst Counter-Strike circles about what was the best mouse to buy. The Intellimouse Optical or Logitech's MX500 were the two favourites. But Microsoft had canned production of the former, and the shape of Logitech's offerings (with the concave indent for your thumb) was very particular, and not at all conducive for certain mouse grips. So if you were in the market for a new mouse, or your Intellimouse had just died, what was a gamer to do?
The go-to mouse became the Deathadder: it had the same shape as the fat Intellimouse Optical mice, the optical sensor was just as reliable at the end of a tournament as it was at home, and it felt good in the hand. Razer's since refreshed the Deathadder line with the Deathadder Elite, and it's just as good as the original Deathadder was over a decade ago.
