Audials Tunebite have 12 purchased directly from the manufacturer (so nich on amazon). Unfortunately, the video recordings bucking very strong - no matter what source (of course, I have ruled out all possible sources of error and a lot of attempts made to produce a flawless recording). So far so good - created error message and provided with all necessary documents. no reaction. So after 6 weeks all repeated - still no response. unfortunately it does not help, the support by email to write directly, also no reaction. which is really weak and very unfortunate. Therefore, only 1 point - unusable.
