Great coffee, a real slice of American food history, you won't regret it.
Positive Product Points
Simple to use, clean up is not a problem. I wonder why this method of coffee making lost popularity.
Negative Product Points
Try to make sure that the gasket in the pot you want to buy still has some resilience to make a good seal.
My greatest joy is with the vacuum method in general. The Cory will meet all your expectations. You can use an ordinary drip grind and you can control the infusion length. You control the brewing process and get just what you like. The Cory rod filter is a brilliant, simple design and no more paper filters to buy. I don't use the Cory for work day coffee at home, At the weekend it's all I use. The pots are readily available on Ebay and you can still get a deal. The vacuum pots are a great connection to our past, and I hope you adopt this method and sit down and ask yourself, 'why am I in such a hurry'? Relax, have a cup of great coffee, maybe a little something to eat. Ignore the clock for a few minutes.
Just some general advice on Ebay. Check the seller's rating and don't be afraid to ask questions. If the pot you want is priced too high, just wait something else will come along.
