Let me write something about the lightest mouse out there, only 63g. First of all, regarding its weight, it will take you a few days to get used to it, be careful, it won't feel negative, but rather strange. However, after that, all the mice you have used will feel heavy! For gaming fps, it is an incredible experience where it responds with unbelievable responsiveness to your movements, what can I say... pure enjoyment! Of course, it is equally flawless for desktop use, browsing, etc. Its sensor, the PixArt PMW3360, is among the top 3 available. Absolute precision, impeccable acceleration, and incredible control no matter how fast your movements are. Its size and shape are very convenient and comfortable, without any strange curves or protrusions, designed to fit many hand sizes. Mine is 19cm long and 9cm wide, but it definitely works for other dimensions as well (the frame has it if you want to try it). The switches are Omron and do not have any double-click issues. Also, the clicking sensation is fantastic, no matter how fast you press them, you don't lose count. Their sound is slightly audible, which I personally like and matches the overall construction. The scroll wheel is light, but I should note that sometimes it deviates, scrolls slightly upwards - all the mice I had did this, so I'm not sure if it's the mice or the software's fault. The build materials are flawless and give a pleasant feeling when holding it. Finally, the lighting is beautiful with many customization options. Don't be fooled by the price, it is one of the most high-quality mice I have tried, and I have tried many. It may be cheaper due to its lightweight construction and because Sharkoon hasn't put a premium on it like Logitech, but it is equal to and superior to much more expensive mice. Buy it without hesitation.
P.S. I recommend pairing it with the Cooler Master MP510-M mousepad, which uses a special fabric that is unmatched, and it is one of the best on the market. The sensation of speed and control is truly out of this world!
