AHS was the first HBS I quit using. Every order came with a different problem of increasing difficulty. The final straw was the whole credit card issue two or three years ago.
One consistent problem across all the orders was that the grain amounts were always off. It wasn't like it was always over or always under, each order would have some grains over and some under. Usually it was just an ounce or two but I seem to remember once or twice it would be off considerably and always under. I thought my scale was broke but it isn't. I usually came out about even between the over and under amounts so I never did anything about it but it certainly didn't curry any favor with me.
