I decided to approach the review as a comparison between this mouse and the Razer Viper V2 Pro. I have a small hand, grip something between relaxed fingertip/relaxed claw - I guide the mouse with fingers that are only slightly bent and the back of the palm lightly touches the end of the mouse. I' ve been using the Logitech G700 and G604 for years in MMOs and RPGs, so I' m very used to their ergonomic shape. When I compare the first impression of both mice, the G Pro Superlight feels better when you hold it for the first time, it feels more natural in your hand. On the other hand, even though both the Razer Viper V2 Pro and the Logitech G Pro Superlight mice are ambidextrous, the Razer feels more ergonomic thanks to the larger depression in the thumb area and the shaped buttons, but not so naturally at first. When testing mice in CS: GO and Overwatch, I would say that the G Pro Superlight is so-called Easy to use out of the box, although it does not feel as ergonomic and light in the hand as the Razer Viper V2 Pro. A person immediately knows how to aim, even when holding it for the first time. On the other hand, if I had to highlight the main advantage of the Razer Viper V2 Pro against the G Pro Superlight, it is the control and certainty, which is immediately much better because of the shape. Think of the value of 100 as a straight line that represents consistency of performances: G Pro Superlight: 98; 100; 101; 102; 99; 100 V 2 For: 92; 109; 102; 93; 100; 111 In short, G Pro Superlight is more casual friendly for most people, right out of the box, V 2 Pro has a higher skill cap, you can achieve better results with it thanks to better control, but also worse because it is not as consistent. Perhaps due to its more ergonomic shape (more frequent overshoot, here and there undershoot, which does not happen with the G Pro Superlight). I don' t know why, but even after a lot of hours, I feel this way about both mice, and even if my results improve after gradually getting used to both mice, the consistency of performance is still the same as I described above, only the numbers would be higher. Finally, I would like to talk about the processing, which is excellent in both, but in the case of the V2 Pro, beware of the extreme volume of the main buttons. When both mice came to my work, I immediately tried them there, but with the Razer they are so loud + such a higher tone and a more crispy sound that it could not be used there without disturbing people, it was also annoying to me that they are heard so much in the pulpit.
