This mouse didn't work out for me, I returned mine, despite loving the coating and glide materials, the thumb grip, concave top and extended m2 felt really good in hand, but the lack of support for palm on the right side ruined everything even tough I was able to palm grip it just barely with 17.5 cm hands.
Its like the right side started really good at the back, but they "laser cut" it to make it uncomfortable on purpose, it just has an empty flat space there, also the front right extends outwards too much and its uncomfortable for the ring finger It does feel OK for fingertip grip but that makes the thumb grip and coating materials useless.
The lip on the mouse2 can also increase the chance of accidental clicks
Very sad because every other detail on the shape was perfect, the side buttons are also really easy to click, due to the sharp edge. And all the coating on sides, top, buttons wheel are unique and feel really smooth.
Also buyers should be aware that ROCCAT claims about using top quality internals are true, (ALPS scroll and TTC side switches) this fact is completely useless because they decided to use 5M chinese omrons on main buttons which should have premature double click problems, so dont expect durability from this one, this was a really dumb and dirty decision, pretty much every mouse above 35-40$ uses at least 10M omrons, and this mouse for some strange reason is very expensive in europe, but costs half as much in US.
The braided cable was annoying and sturdy, it dragged on the pad because it was not tilted upwards like some manufacturers do, the scroll was awesome albeit a bit too hard to click and a bit too far back but I have seen worse.
All the problems with variable DPI and unstable polling seem to have been fixed with latest firmware and macros work without drivers installed as expected.
I never considered ROCCAT a good manufacturer, in the past they used terrible cheap materials and silly shapes for really overpriced mice, even their rubber dome keyboards can cost as much as a 6Gv2.
They got lucky with the Kone and almost got everything right, if it had a proper right side like the one in the Zowie EC2 and flexible cable this would heave been my main mouse for sure.
