I thought for sure I had written a reply for you guys. Must not have hit submit, sorry about that.
3D printing would be too much work for me, I've done projects like that before, and it's a lot of trial and error and a very iterative process - it is for me at least, but my workflow might not be the most efficient.
I tried the G600, I even think it was one of the other options when I originally got the Ikari Laser - I might be mistaken. But it's not the mouse for me.
Never heard of Mionix, checked it out. And holy smokes it looks near identical. The Naos looks a bit bigger over all, but it's worth a shot. I've already ordered one, will check back in with my final verdict when I've tried it out.
