This is a very short review / opinion Logitech vertical mouse.
My daily mouse is Logitech G402 but today I switched it up a bit and used a Logitech MX Vertical. It is a bit different from my standard mouse, I like the idea of a vertical mouse and after a longer period of use I actually noticed how my hand had no strain. But one thing is for sure. I will not switch it up with my G402. The buttons on G402 are much better quality and also I find the vertical mouse a bit too narrow for my hands, I just didn't feel it 😊.
TL;DR Great mouse but try it before you buy it! 🔥
