Oh boy, there is so much wrong with this statement.
1. Corsair scrollwheels are notorious for just breaking after a few months.
2. The Icue Software is the worst Software I have ever used. Took me 3 youtube tutorials to learn how to make macros. With Razer and Logitech its just super intuitive and takes 20 seconds.
3. Corsair Mice have premium prices but feel like cheap plastic toys.
On topic: I can understand your frustration with Razer. Their stuff is just garbage. Unfortunately if you want a Naga style mouse you pretty much have to go with a Naga, Corsair Scimitar, or Logitech G600. Or some cheapo 30$ brand. But tbh it cant be much worse than Razer or Corsair.
The G604 is a good MMO mouse with less buttons but its really heavy and it uses AA batteries. WHAT YEAR IS IT?
I would recommend using a mouse with less buttons like the G502 and using the mouse buttons a modifiers. Takes a little time to get used to but you are not depended on a Naga style mouse anymore.
