I would suggest searching in the main thread for scan bran (and also recipe thread - there are quite a lot of recipes that use scan bran). Opinions differ wildly on the taste. I can see that some of the posters above like it. I personally think that it tastes nothing like ryvita and would liken it to cardboard that has been left in a dusty attic for a few months - nothing that I've tried so far has made it much more palatable. I tried 2 scan bran cakes - 1 was horrible, the other one I overcooked. So I have 1 more packet at home to try and if the cake doesn't work or the ferrero rocher things, I won't be buying it again.
However, as you can see from above, some people have great results with it. So, maybe try it and see how you get on.
