SteelSeries Sensei 310 at first glance seemed to me a bit strange rodent. His whole life was spent working with asymmetric mice, so the very sight of a symmetrical device heralded that there was something new waiting for me. The first impressions of Sensei 310 were extremely positive. Subdued design, characteristic for the brand plus backlight, which you can freely modify (or turn off). A solid rubber cable and something I missed in my younger brother, Rival 110 - nice silicone finish on the sides of the mouse. A sure grip and a great look in one. The shape is very similar to the previous model series, so that the Sensei 300 users taking the hand of the 310 model will feel "at home". The mouse is large and probably lies in the hand - for people with larger hands is an important advantage. Sensei 310 does not frighten the user with an excess of buttons - there are 6 of them and that's enough for everyday use. They work stiffly and with a slight resistance, which minimizes the risk of accidental insertion. It's hard to write something groundbreaking here, everything just works as it should - the only minimal flaw, or perhaps more caused by my habits, is the somewhat too hard to touch scroll. However, I can not accuse him of anything but a subjective feeling. Rodent tested on several surfaces and Teflon sliders fulfill their task one hundred percent, although today in this segment is, of course, a standard, not a thing worth special attention. The sensor definitely deserves this - TrueMove3 is fast and precise, regardless of the conditions. I was very surprised, because until now, as a mouse for FPS, I used equipment that was considered one of the best on the market in terms of quality and precision of the sensor. SteelSeries announces a bit buoysily in the ad that Sensei 310 TrueMove3 transfers our 1: 1 moves to the virtual world. I must confirm this and add that it also makes it very convenient!
