I don't have his trimmer as I already had a modified Gracy before the Giraud trimmer came out. But I do have his annealer and it works as advertised, and just like the trimmer, it's built like a tank. It is also adaptable to just about any cartridge case with very few extra parts, unlike some other brands.
The annealer is designed to use the short, fat camp stove propane bottles. If you have a very large number of cases to do, you will want to buy an extension hose and use a 20lb. BBQ grill propane tank as the flame decreases as the pressure drops in the camp stove bottles. Not an issue unless you are doing very large batches.
My experience with Mrs. G mirrors yours. She was very pleasant, had answers to all my questions, and went out of her way to accommodate my delivery request. (which saved me the shipping charges) They are great folks to deal with.
