I've buying this, and the chicken version, for my cat for around seven years. It is the only food she likes to eat (she is very fussy and will not touch canned cat food ... not that I can blame her). She is in perfect health, and for the sake of an indoor cat where I have to scoop everything out of her litter tray, she does perfect poos! What more could you ask for?
My cat loves it, it doesn't stink out my apartment, it is made in Australia, it comes in big bags so you don't have to buy it often.
It would be nice if my local convenience store sold it rather than having to go to a Pet Shop.
