So, any thoughts?
I have to say I'm pretty impressed so far, coming from a good old G400.
Perfect shape, low weight, very accurate (more so than G400), good glide, good weight balance, nice clicks, low lift-off distance, better Mousewheel (silent, doesn't skip steps), flexible cable (despite clothed) and it looks business enough to keep it on the desk.
Feels just a new and refined G400, wich is exactly what I was looking for.
