That's not true. It depends on your grip. Me, with fingertip grip, was using FK1 for over three years, until it broke. Now I'm using G402 for like 6 months, but can't use this shit with my grip. I'm gonna switch back to Zowie mouses, but I'm gonna check out ZA11, because my cousin uses it and it fits well for me. I also had EC-1A, but this mouse isn't for fingertip, more for Claw/Palm.
Make a good choice.
