Since my old mouse is almost not usable anymore, I decided to buy a new mouse.
But this time I will buy a more expensive one, I searched for a long time, and my desicion will be under those 2 mouses:

The Logitech G500

And the Roccat Kone+

I cant decide which one to buy, please help me with your opinions
