So, I emailed the support address on Func's site some time ago. It turns out, that's not the right email for US support. If anybody else is having problems in the US, use firstname.lastname@example.org as they are MUCH more responsive and quite friendly. They sent me out a replacement immediately (they said the return can wait), acknowledged the problem, and are sending the newest revision of the MS-3 with the scroll wheel and various other fixes. Customer service is *almost* more important to me than product quality and if their new product really is an improvement on the original MS-3 then I'll be quite happy with Func overall.
