= Sounds - I can not attribute this item to pros and cons, it's just neutral. All sounds are nice. They don't distract at all. The wheel, of course, is a little louder due to the fact that it has slots. But I like how it sounds when you press it (SCM). LMB clicks well, the sound is pleasant, I like it the most) RMB has a little louder and louder, but this is the case with all mice. = Material / coating - everything is fine with it, I really liked it. Hands do not sweat, nothing sticks. I don't notice any dirt yet, let's see how it will be)) Let me summarize. I took for a price of about 3.5 thousand. For such a price, just a gun. To customize for yourself and adjust the backlight, you need a proprietary Razer program, I wrote about it above. With it, you can "pump" for the most comfortable use for you. There are also different profiles and the ability to create them, including for backlighting. Considering that I had never taken the products of this company before, this one surprised me. Hope it lasts a long time. Thank you for reading)
