Scanners, software, and support very well

Last week I ordered the scanner despite my concerns because of the negative reviews. After extensive tests I am completely convinced. Installing under OS X 10.8.5. on a Mac Mini with 16 GB made no problems, the update of SilverFast could be installed quickly. The scan results are visible from a higher quality than that of Canon 9000 F Mark II, with a slight reworking with DXO or Lightroom they improved even further. The smaller the files, 550 MB per scan at a resolution of 7200 dpi and a color depth of 48 or 62 bit easy reach! I can only report positive news also use telephone support SilverFast: I was immediately connected, answered my 2 questions immediately satisfactory!
Strong buy recommendation.

Supplement after a few weeks of intensive use:
The scan times with SilverFast are extremely long (20 minutes at full resolution). That I could get used to considering the very good result. Pronounced annoying however were the regular program crashes, about after every 2nd to 3rd scan. So I did not want to work! I then purchased VueScan, it is stable, the results are comparable and the scanning time is about 7 minutes. I can also use it for my Canon 9000F.
Now it works !!
