To be honest, I don’t understand why the third button (under the ring finger) is not made in all mice. It's super convenient, once you try it it's impossible to use other mice. This button in almost any application performs the "back" function, for example, in the browser it returns to the previous page, in the explorer to the previous folder, in spotify / i. Music / discord - the previous state, etc. Plus, you can assign a function to this button yourself, for example, in games it is an auto attack or a close attack, in general, any frequent action. You can assign other common actions to side buttons, such as closing a tab in the browser, opening a closed tab, fast moving up or down the page, and so on. About games, especially mmo, I think everyone understands that. Even the farthest buttons are surprisingly comfortable to press. I've been using these mice for 10 years already, and I've changed 5 of them. What's more, I bought them in different parts of 2022 and even abroad - they all have the same poor quality. And even in completely new mice, buttons can be pressed differently - somewhere tighter, somewhere easier. The main problem is the low resource of the buttons, double clicks appear or you have to press with noticeable effort. Because I have already accumulated quite a few of these mice, I just re-solder the buttons. On average, a mouse lasts from a year to 3 years.
