As with all of the SteelSeries mice I have had the pleasure of using, the Sensei [RAW] is just as agile and light as you would expect. I can't say much for the shiny version, but the grip and comfort of the rubber coating on this version made the mouse easy to lift and even with sweaty hands in this warmer weather, I wasn't sliding off the mouse or missing clicks in gaming situations. For someone with a medium sized hand, the Sensei [RAW] will be a comfortable fit. I even took a couple of days with this mouse in the left handed setup and the ambidextrous nature of the design feels exactly the same for both hands. The shape and contour along with the rubber coating really "just fits" without having to jockey your hand around for just the right comfort zone.
Mechanically the Sensei [RAW] is very solid. The mix of Omron and TTC switches on the inside are solid and I couldn't get them to miss a click with the software running to verify my testing. While the Omron switches are rated for a longer life, in my short time using the Sensei [RAW], I barely put a dent in its lifespan and really see no reason not to put more expensive switches where they aren't used as much. The Avago sensor is plenty for anyone with the 5670 CPI top end. I tend to prefer mice on the higher end, but as much as I tried, I could not get used to the super responsive nature of that setting as I overshot enemies. This is where that CPI switch comes in though. Even at the basic level I could still zoom around the desktop and with the click of a button I trimmed down the sensitivity and got my gaming in with much better control.
While I was only left one choice of lighting, the white parts that do illuminate really accent the matte exterior of the rubber coated [RAW] very well. I wasn't much of a fan while typing of the breathing mode, it becomes a bit of a distraction, but during gaming or between rounds or maps, the pulsating lighting effect is a nice option to have for those who can appreciate it. There is also a mode where the lights will flash with the left click button, but at that time you have your hand covering most of what illuminates. The ARM processor and its stack of onboard memory got removed, but the 16-bit sensor is plenty for what this mouse was intended for.
The best thing about this is you can get the Sensei for much less now if you opt for the [RAW] edition in either form, it will only cost you $59.99. To step into what makes professional gamers as accurate and deadly as they are with such a drop in pricing over its predecessor, this is the perfect time to experience it for yourself with the SteelSeries Sensei [RAW].
