I love Roccat and the fact that they have software support for Linux, even if it's unofficial. Unfortunately most of the gerbils they offer are just too small for my hands, I recently returned a Kone Pure and was recommended a Kone XTD by their support, but it's a bit too simple for me, too few buttons. This one is also a bit too small judging from the specs.

Also, I hope someone will take over the development of the Linux Roccat tools so that current and future devices will be added again, like the Leadr.
