Hi! I love my Naga mice. I have two classics, a 2012 and I just bought a Epic Chroma. The 2012 is good but it had an issue where, if plugged into my Mac at boot, it makes the Mac think the control key is pressed, so I cannot enter passwords into the EFi FileVault login. So I bought a Epic Chroma. I like the speed and fluidity, but I am having two major issues: 1) The 12 pad is not laid out in an arc like earlier Naga nice. The key layout is square. This means I am constantly pressing 9 instead of 6. I really preferred the more natural arc button design as a thumb moves in an arc as you move it up and down. I am not sure why this design decision was made. 2) The buttons on the 12 pad are so easy to click that when I go to move the mouse to the right, or tilt the scroll wheel to the left, I am pressing a 4 or a 7. Is anyone else running into these issues? Do they go away with practice?
