Cannot import;
Slow page rendering;
No function besides turning the pages (which, as I mentioned, is slow).

Does the job

It works with some djvu files (some of which turn into literally multi gigabyte files when converted to pdf) for which pdf conversion is not an option. To be honest, when I read scarce few but very negative reviews for the past versions, I was hesitant to pay for this app. But the price was low enough that I took the plunge. I load files via iTunes file sharing and it works fine (IOS 5.0.1, iPad 2), and I haven't faced any problems with the files I tried to open and read with this app (of course, your mileage may vary). I am a happy customer. I give it five stars (based on basic functionality only: I don't care about the UI bells and whistles for this particular use case, so I am not the person to comment on that).

Does not work

Tried everything, which isn't saying much since it only allows you enter a url. I entered a valid DjVu and it did nothing.
