I can’t say anything about reliability, because I only used the mouse for one day and handed it back, because it turned out to be too small. The mouse is suitable for people with an average or smaller palm (> 18 cm), because despite the length of the mouse at 130 mm, the actual working surface here is approximately 120 mm. due to its form. I really liked the behavior of the sensor in games and how the mouse glides across the carpet. I did not understand the polling frequency of 2022 Hz at all, because in games, the mouse behaves less obediently and is very unusual. (I personally thought so). At 1000 Hz everything is fine. I liked the backlight, it is distributed evenly and you can separately adjust the backlight of the scroll and the logo. The mouse left a good impression, especially the technical component.
