My ZELOTES F-35 Wireless Rechargeable Vertical optical Gaming Computer Mouse after 2 years of use

I have never used vertical mouse before, reviews said it is hard to use, but it was so much easier and more comfortable than the regular mouse - no adjustment at all, much better.
My only challenge is that because I do not use mouse pad my skin rubs against the desk, I wish there was a cushion between the hand and the desk, but really the mouse is great and I love it.

I started using this mouse as soon I got it in 2019. I use a computer for 8 - 11 hours/day and had some strain on my wrist as a result. I switched to this mouse and it made a world of difference!
It took some time getting used to it at first. How it moves around will feel different because it's a vertical mouse instead of a flat, horizontal one.

Once you learn how to use it, you won't want to go back to a regular one!
