- Long working time. Massive scroll with good inertia. Additional keys do not interfere (except for the side scroll). Heavy.
- The inventors of the side scroll should burn in hell! Because of it, it is impossible to use the middle click, and this is the second most important button in the browser and in all CAD systems (rotations, zooms, that's all through it). Yes, you can disable them in the program, but you will have to keep the proprietary software in the background. The mouse is not cheap, they could do internal memory as in the G series for settings.
