Thats for the specs realy..
Ok.About the casing it looks something like this

Its contains:
1.The mouse itself
2.The Box.
3.The Master Guide
4.Certificate of Authentication
5.Introduction manual
6.And a razer deathadder speech about it
Here's the pics(note that the black razer envelop contains 3-5)
Some say it may have sticker.IT MAY

Then,
The Mouse design is said alredy.Its for right handed gamers only.I MEAN ONLY because i tried it with my left hand.It SUXXX

The side buttons are dust collectors.So make sure you keep away if you pick your nose or swipe you sweat

COMPARISON
i compare the size with a optical mouse which is found everywhere..(I got the genius from popular

)

Well,The size is quite big and for those who wanted to buy DA..I highly reccomend u tried it first.
The other thing is they have Teflon feet.(note that teflon feet glide for accuracy.The genius mouse feet only glide effortlessly which may lead to disaster to game)

The Sensor.
The sensor CAN be seen by human eye!!!

Beware.Its not very obvious.Tilt you mouse 45 degree from the front and you'll see the red dot.Yeap thats the 3g sensor.Enjoy

)Like this

Lastly...
All i wanted to say is..This mouse is good for low sensitivity users who wanted to kick ass in cs..I wanted to change to lachesis but the mouse is good enough for me so i have no reason to change now.For new DeathAdder users.You might think that its same with other mouse but!!!when you tweak it a bit,You see that your mouse is very precise.(note that the world's living legend..SK-SpaWn uses only 900-1000 dpi only

)Isnt that prooves it.
For those razer haters..All i wanted to say is that you may have bad time in razer products but i can assure you,it depends how you take care of the mouse and what condition you put in
Way to Elongate the Mouse's life.
1.The rubber topping is just a TOPPING it may come off so,wash your hand before using it or just clean the mouse with soft cloth or smooth tissue(NO toilet rolls please!!)
2.The Sensor cathces dust easily.Use a cotton bud and dip it into a little bit of WARM water and just clean it.(DONT POOK IT)
3.Use mousepads.For me im still using steel series QcK....Never use it on any hard surface like wooden table or SAND PAPER to test it.It wears your mouse feet away in less than a month.(from my friend)
That's all folks hope you enjoy the review
