Even though the focus ain't the look, lets start with that anyways. The mouse is bigger than most other models, and it takes a bit of time to get used to it, but when you have been used to a mouse in that size, you just can't use a computer mouse that ain't in that size, both positive and negative. The Sensei is made for every size of hand, and works for both left- and righthanded persons. The mouse got eight buttons that you can program just the way you like with the free software Steelseries Engine provided by Steelseries.
The surface of the Sensei is silver and got black sides and a black bottom. On the back of the mouse is the logo of Steelseries. Under the mouse is there serial- and productcodes and in addition some gimmick, that is a LCD display, and you choose what the display has to show, all by yourself. The wire is braided and is good quality like everything else on the mouse.

Functions

As said earlier the mouse have 8 buttons that you can program to do almost everything. The magic happens in Steelseries Engine, that you can get from the Steelseries website.

Additionally you can change the speed and the colors of every light. 16.8 million different colors, so it can be hard to choose.

As standard the buttons are:

1. Back (in the browser)
2. Forward (in the browser)
3. Leftclick
4. Rightclick
5. Scroll
6. Scroll up
7. Scroll down
8. Change speed

Advantages

• Cool design
• Fits in every hand
• Customize it to be your own in every possible way

Overall the Steelseries Sensei is a really great mouse, that really fulfill every demand a consumer would make. It fits perfectly in your hand, you can change the speed in no time and last, but not atleast, you can make it personally by change everything about the mouse. The Sensei keeps standing, even against cola, strawberry cake and other stuff that shouldn't be there.
