You're right, they're not as bad as I initially experienced. My mousepad was a bit dirty. I actually don't have a problem with them now. As for the LOD, it's actually not that bad now that I'm getting used to it.
As for the shape, I think it's great apart from the thumb rest. It forces me to grip it in a way that I am not used to and not the most comfortable with. Still feels better than the AM though.
Either way, I'll be returning this mouse in a couple of days to a week. I want to try the Zowie FK and Kana V2 first, or atleast one of them before I make a decision. The Savu was originally going to be the last mouse for me to try out of these 3, but it just happened to be available at a local retailer so I decided to pick it up. Way easier to return. Definitely a good first impression with Roccat though , if I end up liking it the most out of the three I won't hesitate to buy another and get used to the thumb rest.
