No don't ever get that mouse.
Yes you're right, dont' get the new Razer mice, they suck big time and it has no difference or maybe only slight difference as compared to their predecessors.

If you want to get locally :

Steelseries Rival/Sensei wireless
Logitech G400

If you can afford to pay the international shipping fees from Amazon, get :

Logitech G400
Mionix Naos 7000

G700s has very sucky battery life according to many people. Some say a few hours already mati, some say a few days...

Why don't you opt for G602?

Do steelseries sensei wireless available here in malaysia? cant find any seller...

Planning to get a high DPI mouse since I m using 3 monitor. Considering between Razer Ouroboros and Steelseries Sensei Pro Laser series mouse. Can anyone tell me why the sensei series price ranging different so big, Rm250++ ~ RM400++, what is the biggest different between them?

BTW, I just need something fast and help me aim more precise.
Of couse, it must be good in holding and light weight. Currently active game is BF 4.

I have NEVER EVER accidentally pressed the buttons on the left side of the mouse. Your thumb rests at the bottom of the buttons nicely. Logitech did a good job in this aspect - comfort and usability.

Now i am stuck in between Ouroboros, Sensei MLG edition, and Rival.
Rival spec and price is just surprising me, but the sensor is 6k DPI instead of 8k like the other two mouse which stated above.
And the only thing that ouroboros attracting me is just the DPI and zero lag wireless, I'm not really convince by the customizing design and in fact, i hate the robot holding feel.

Senser MLG spec was fully filled up my requirement except for wireless function. With the same price, i can purchase the high end wireless mouse as well (Razer Mamba, Ouroboros, RAT9), so... really hard to made decision on it..
