Bottom line: design and PR are on top as always. And the sensei series has always stood out for the quality of the sensor. I can also note some tightness of pressing the buttons. If you're jumping from your old, slightly "worn out" mouse, whose buttons are already easy to press, then this mouse may seem rough to you, but it's all a matter of taste. I can note a very impressive size, but this is also all subjective. My main complaint is the build quality. For the impressive price, the mouse is built terribly, which is why I recommend that you either think 10 times before buying, or choose another mouse. I myself will most likely return it, tk. creaking throughout the room through full-size headphones is no good.
