These filter cones are the quickest, easiest and cheapest way to make filter coffee. I already had a porcelain cone, but found it had a very slow filter-rate. This one is much quicker - you can have a cup of filter coffee within 30 seconds of the kettle boiling.
Since it's Melitta, it takes the Melitta filter papers perfectly, and feels pretty robust and should last for a while. A fiver is an ok price for it too.
If, like me, you lack the patience to faff around for ages making filter coffee, this is a really good solution.
