The DeathAdder 2013 is made for right-handers. The casing is fairly hard and a bit rough, but the advantage of this type of body is that it'll keep your hand from sweating. That's a definite plus for those who spend a lot of time on the computer.
To further improve handling, there are two textured rubber side grips exactly where the thumb and ring fingers fall on the sides of the mouse.
At 12.7 cm long, this mouse fits nicely in your hand, but it's not quite long enough for users looking for more wrist support.
The DeathAdder 2013 has a sober and elegant design, and it isn't decked out in a load of LED lights. Only the Razer logo and the sides of the scroll wheel are illuminated.
The feet keep glide smooth and silent, and the optical sensor works pretty well on a range of surfaces. You'd need to put the DeathAdder 2013 on an extremely shiny surface (on a tablet screen, for example) for the sensor to stop working.
However, the buttons aren't quite as impressive. There are five in all: left and right buttons, a notched scroll wheel and two thumb buttons. If we add the "scroll up" and "scroll down" functions, then there are seven controls, all of which can be customised using the software supplied. Note that the thumb buttons are easily accessible but quite noisy when pressed.
The DeathAdder 2013's driver allows you to independently configure the buttons with different functions, actions or macros (sequences of actions). You can also change the sensitivity level from 100 to 6400 dpi. However, seeing as there are no specific buttons for sensitivity on the mouse's casing, you'll have to assign the increase/decrease dpi functions to the two thumb buttons if you want to change sensitivity on the fly. That's a bit of a shame.
With a maximum polling rate of 1000 Hz, the DeathAdder 2013 will satisfy most day-to-day users (office computing, web browsing, etc.) as well as those looking to work with greater precision (gamers, graphic designers, etc.).
A gaming mouse needs to track movements
of at least three metres per second. The DeathAdder 2013 can track movements up to 3.7 m/s.
