"There have been a raft of mice that enable the user to customise the buttons, or the colours. Record complex macros. Store multiple profiles. However we can't think of any that have done it so brilliantly as the Sensei."

"It looks the business, works flawlessly and has customisation options coming out of its ears.

This is currently our favourite mouse on the planet and it will take something very special to knock it from the top spot. "

"Amazingly, this could be the most comfortable mouse I’ve ever used. It doesn’t cushion your palm that much, but it’s plastic back is soft and smooth, so much so that you don’t need padding. "

"It comes with ridiculous sensitivity options, great accuracy, impressive features, well thought out and simple software and it’s incredibly comfortable to boot."

"SteelSeries Sensei is the best mouse I’ve ever tested."

Hardware Heaven

"With such a massive level of configuration for CPI (available in increments of one) the inclusion of a button to switch between two pre-set levels is very much appreciated and one of many aspects which demonstrate how well thought out the mouse is overall. No doubt a reflection on SteelSeries getting the input of over 25 top eSports players during its development."

"The SteelSeries Sensei is the most powerful mouse we have tested to date. An epic product from SteelSeries."

Bow to the master.

Since the release of our first mouse, we have been using Japanese-inspiration in our naming of them. Our mice are built for performance and tournament-style play; Ikari means anger, Xai means talent, and the list of product names goes on. The Sensei is our version of the grand-master in our Do Jo. It is the teacher. The one everyone bows to, the one who knows tricks and secret moves that everyone wants to learn – but so very few can ever hope to master. It’s a fitting name. Master your game. Meet the Sensei.

WINNING, IT’S THE WAY OF THE SENSEI

The name fits because everything we ever learned about mice, everything we ever researched, everything we ever discovered, everything that makes a mouse great, is exactly what we built the SteelSeries Sensei around. The DNA of Sensei is programmed to win. It is one of those rare hardware products forged by love and science, trial and error, passion from professional gamers and a desire to push the envelope. SteelSeries Sensei was born for tournament victory; it was built to help you win.

SIZE AND WEIGHT

• Weight: 102 grams (0.22 lbs)
• Height: 38,7 mm (1.5 in)
• Width: 68,3 mm (2.7 in)
• Length: 125,5 mm (4.9 in)

SteelSeries Sensei can be fast, like really light-speed fast, if you need that kind of speed. Because we use a 32 bit ARM processor in the mouse, we can double (x2) your mouse sensitivity.

Our default CPI range: 1 to 5,700 CPI.
Our Double CPI range: 5701 to 11,400 CPI.

This feature is particularly useful for people using multiple monitor and similar environments.

BEST-IN-CLASS TECHNOLOGY

Featuring a state of the art laser sensor that offers a consistent and reliable performance, the SteelSeries Sensei boasts 10.8 megapixel HD image correlation at up to 12,000 frames per second and the ability to handle tracking movements of up to 150 inches per second.

ADVANCED MACROS

Thanks to the support of the SteelSeries Engine software, you can record even extremely long and advanced macros to the Sensei. The macros can be layered and can include keystrokes and precise timing. How you will decide to use this advanced feature is up to you (choose your configurations wisely and adhere to any rules that you may need to abide by during gameplay); we are only presenting you with the capabilities for endless possibilities.

TO CORRECT OR NOT CORRECT?

SteelSeries FreeMove eliminates path correction, which makes the mouse predict, correct and make your movement straight. With the SteelSeries Sensei, you can adjust the amount of path correction or completely disable it for 100% control of your movement.

32 BIT ARM PROCESSOR

The processor in SteelSeries Sensei is a 32 bit ARM processor and it is as fast as the original Pentium 75 MHz processor released by Intel in 1994. That is fast, incredibly fast. This reference may sound like overkill, but it’s this type of power that allows us to do sophisticated calculations directly on the mouse – without the need for software drivers and without having to rely on the user’s computer.

Our industry leading ExactTech settings, like ExactSens, ExactRate, ExactAim and more, are calculated directly on the mouse providing the user with a mouse movement that is completely free of any interpolation or extrapolation, without any delay, filtering and without using up memory or resources on the user’s computer.

STEELSERIES EXACTTECH

Complete customization of the Sensei’s can be configured through 4 technology features that we’re calling SteelSeries ExactTech settings.

EXACTLIFT: ADJUSTABLE LIFT DISTANCE

The Sensei gives you the ability to customize the lift distance. This has a number of practical applications, most importantly it allows you to fine-tune the mouse to your preferred mousepad or mousing surface. Not all surfaces are equal. Surfaces are made of many different types of materials and those different materials have different qualities. They can be reflective, rough, smooth… the list goes on. All of these factors will influence the lift distance of a normal mouse; with the Sensei, we put a whole new dimension of control in your hands.

EXACTAIM: SLOW DOWN AND FOCUS

SteelSeries ExactAim will allow you to be more precise. Headshots anyone? As you slow down your cursor the mouse will decelerate even more allowing you to focus on your target.

EXACTACCEL: MOVE FAST, NO EVEN FASTER

SteelSeries ExactAccel does just the opposite as ExactAim. As you increase the speed of your mouse movement, ExactAccel will accelerate your movements even faster in order for you to move across your game or page faster.

EXACTSENS: CONTROL THE SENSITIVITY

SteelSeries ExactSens allows you to control how fast your pointer should move by adjusting your CPI in increments of 1 between 1 to 5,700 CPI. This means, the SteelSeries Sensei offers you true hardware based sensitivity settings, freeing you of interpolation from game software. To really get the full benefit from ExactSens you need to deactivate any cursor acceleration and set your sensitivity settings in-game (sensitivity 1 or adjust your sensitivity slider to lowest possible setting) and on your operating system to default. You can use the CPI calculator below to find the value that resembles the cursor speed you are used to, giving you a good starting point for tweaking your sensitivity to perfection.

We are proud to be associated with some of the best players in the world of eSports. We maintain strong relationships and have continuous dialogue with teams like SK Gaming, Fnatic, Evil Geniuses, Natus Vincere and others who help in the development and improvement of our products.

To ensure maximum performance in all gaming scenarios we enlisted help from world-class StarCraft® II, Counter-Strike, Quake Live, DotA, League of Legends, Heroes of Newerth, WarCraft® III and Doom players. Click on the picture below for a list of the players who helped us with testing and refinement of the Sensei. We owe them a lot of thanks, so if you like the Sensei these are the players that helped make this mouse what it is.

ON-MOUSE LCD MENU

With the LCD display on the backside of the SteelSeries Sensei, you can customize all settings to fit your specific needs. The LCD menu offers setup of even the most advanced ExactTech settings described on this page.

MAKE IT YOUR OWN

It also allows you to upload your own bitmap picture, offering a great way to personalize your mouse – and help prevent theft at LAN-events, gaming cafes and other public places.

GLIDE LIKE THE WIND

Material: Gaming grade UPE covers 16 % of mouse bottom to ensure maximum glide. We recommend changing glides regularly as they will eventually be worn down.

3 different zones on the Sensei (the wheel, the CPI indicator and the back) can be programmed individually – in 16.8 million different colors. It’s another way for you to personalize your mouse. It also brings a very real benefit to users who utilize multiple profiles: by giving them different colors, you can quickly switch between profiles and also ways know which profile is active. For those of you who don’t like glowing shiny stuff on your desktop, you can completely switch off all illumination.

There’s no need to install software of any kind in order to use the Sensei. The built-in driver can be adjusted through an LCD menu on the backside of the mouse. Simply plug in the Sensei and play. For the PC Gamers* who want really advanced customization options, the Sensei is supported by SteelSeries Engine technology.

SENSEI COMPATIBILITY

Operating systems:

WHY YOU’LL WIN

Will the Sensei make you a badass 1337 n00b-owning gaming hero? Probably not, sorry. A mouse is a tool, like any other tool. Even the very best, most expensive, most amazing tennis racket in the world will not make you a better user of the tennis racket. Nothing, except your own talent and dedication will do that for you. Any company or product promising that is full of it. Period.

But will the Sensei help you win? Yes, for sure. And that is our promise to you. That is why we built the Sensei. With second-to-none accuracy during movements, it will give you precision down to the level of a single pixel. A 32 bit ARM processor powers the most sophisticated gaming mouse ever built, enabling advanced on-mouse calculations allowing unprecedented personalized setup and extra functionality for all 7 buttons. The comfortable shape with the slick non-slip metal coating and the ergonomic button placements will help reduce wrist strain, allowing you to be faster, more accurate and play longer.

Gearing up for victory

For the remainder of 2011, Sensei will assist players on their road to glory at the Electronic Sports World Cup, World Cyber Games, Major League Gaming Pro Circuits and more.

Xai twin?

The Sensei features the same ambidextrous shape, LCD screen and on-board menu system as the Xai Laser Mouse. Other than that, Sensei is a completely different package.

Made by professionals

Over 30 professional League of Legends, StarCraft II, Counter-Strike, Heroes of Newerth, WarCraft III and DotA players helped develop the Sensei mouse.

World’s most customizable

Yep. Fact. Fully supported by our SteelSeries Engine software, the Sensei mouse unlocks an almost absurd amount of customization options.
