Query: Good Gravy?

I bought this for my grandmother a few weeks before Christmas 2001 in anticipation of a lovely slap-up turkey dinner with lump-free gravy. I'd read a previous customers review claiming they'd bought it and it had revolutionised their Sunday lunches, but I have to say I was very disappointed. Not only was the gravy still lumpy, but it was cold, and hairy. I wouldn't buy this book again.
