SteelSeries Sensei Wireless review

What is that you have in your hand right now? Probably your right hand, unless you are a poor left-handed person like me. No, not *that*. Yes, you have a mouse nestled under your palm, getting ready to click on minimise or another tab you have open in your browser. It feels good right? It is important, due to how much time you use it everyday. Some of us more than others, if you are a PC gaming addict.

You need that device. It connects you, it is an extension of your will, executing your every whim and – oh damn the dog chewed my mouse’s cable in half. Now what? Go wireless? As with every wireless device, there are a few very important factors to consider: battery life and polling rate.


I will admit that I expect a lot from devices when it comes to battery life. While a lot of people are happy with a two to three hour battery for a device used for gaming, that just doesn’t cut it for me. A weekend of gaming should end when you give in, not when the lights on your peripherals fade. Swapping batteries mid raid / game / boss fight is enough to make pretty much anyone rage. The Sensei wireless sports a rechargeable battery that can withstand 16 hours of sweaty palm action.

The wireless receiver / charging plate handily glowing to show the health of your battery. If you really have a marathon planned and you cannot activate any of the battery power saving measures, you won’t ever get caught sans battery power thanks to a handy micro-B USB port that steals the cable from your charging plate and turns the mouse into a wired charge-while-you-play device. A handy locking clasp stops the cable from any unplanned escapes, letting you focus on what matters: clicking. Click you shall, as the switches in this mouse have been tested up to 30-million clicks. Even a pro StarCraft II player will have a hard time wearing this mouse out.


How does a mouse get up to 16,400 DCPI? It uses a Pixart ADNS 9800 laser sensor to ramp the CPI up to 8,200, which is already a mind-boggling number, considering 1,600 feels comfortably quick enough, with 3,200 reaching the point that your cursor can cross the screen with about 2 centimetres of movement. At 16,400 DCPI you can throw that large mouse pad away, because this laser mouse won’t leave and area bigger than a R5 coin. Seriously if you use your mouse on this sensitivity, I want to have a talk about it. The Sensei allows you to adjust from 125Hz to 1,000Hz polling rate,  meaning you will have a hard time blaming your mouse for any mistakes.



The Sensei is the most (non-physical) customisable mouse ever. What do I mean by non-physical? The Sensei doesn’t make use of variable weights or expanding joints or exchangeable parts to get the job done. Everything that you want to change can be changed by using the SteelSeries Engine to communicate with the 32-bit ARM processor in the heart of the mouse. Yup, that is the same processing power inside your mouse that the 75MHz Pentium 1 had. This processor then handles various calculations immediately on the mouse, so that there is no delay due to software on your PC having to calculate adjusted CPI (counts per inch), lift distance, angle snapping and much more. This makes for a much more reliable, repeatable experience with your mouse. It also means the processor can double its sensitivity to a stupendously twitch-gaming 16,400 DCPI.

[toggle_simple title=”What’s in the box?” width=”Width of toggle box”] The Sensei comes in a no-nonsense box that includes the mouse, the charging plate, a 2m long braided USB cable, a SteelSeries sticker and a basic explanation leaflet.   [/toggle_simple]

The downside of all of this amazing tech inside a wireless device good enough to make me consider moving over to wireless? The price. At R2,000 this is a pretty expensive peripheral. But then you remember how often you have a mouse in your hand and how important getting every click on target is. This is a tournament grade mouse, complete with all the goodness from the original Sensei, made with a wireless that performs.

If it has the letters RPG in it, I am there. Still battling with balancing trying to play every single game that grabs my interest, getting 100% in a JRPG, and devoting time to my second home in Azeroth.
