Dont worry about the reviews at Download.com I am involved with Custom Reader and the review was very biased from a competitor. I can show you lots of websites (extremely large) who are using this reader at this time. Never take anyones word for how a software works until you try it yourself. The reader has everything you could want in a reader and even deals with all security problems you will get in other readers that could be extremely dangerous to your users.
Not to mention you brand the reader in "real time" from an online control panel. It is even capable of reporting statistics from your users if you/they so choose. Try a search in google for democp and you will see the online manage panel.
