Summary: I purchased the BulletScan S300 from Amazon in December of 2010 for 262.99. It fit all my requirements, and at first I was thrilled. Then, after nearly 2 years the ADF Roller needed replacing. So I contacted ivina.com in late September 2012. They said they would not sell me a roller. I was told to send it to them for repairs. If the scanner was purchased w/i 2 yrs, then the repairs would be covered by warranty, otherwise repair costs would depend on the issue.
Summary: I still have not yet figured out how to get the software to work as the instruction manual indicates it should. I've had one interaction with their tech support and didn't get much help. Will have another one soon now that I know some of my settings are correct (which the tech support suggested might be the problem). I should say, however, that the scanning function is great. Very fast and good document handling.
