Basically, this is a very good product. Two stars I was only because I was sent on bovine ear bottles which have been stored in my opinion wrong. Compared to other bottles I already own the broth dropped sharply to a lateral side (even by shaking dissolves these no longer), on top of the bottle is strong white Vertrocknungen have formed, the liquid is reddish rather than more transparent , Cattle ear believes that everything is OK and the product will naturally back (they also have), but shipping costs will be borne by me. I am of the opinion that in such a case, the shipping costs must be taken (despite repeated contact they remain in this opinion). This is certainly the last time that I have ordered something for cattle ear !!!
