I've had an Aeropress now for a couple of years. We never make coffee any other way. I have literally lost track of how many people I've made coffee for who have gone on to comment on the flavour and ask how it was made.
It does use a fair amount of coffee, but I just buy the beans in Ikea (super cheap) and put them in a grinder (fairly fine grind - cafetiere fine, I would say - espresso grind is too fine). As I say - always gets positive comments from visitors.
My technique is to fill the Aeropress with about 4 scoops of ground coffee, then fill the plunger with cold water to mark "1", top up with boiling water and add to the coffee. (Boiling water makes your coffee bitter, hence the cold water). Press down for 10-15 seconds, over an insulated coffee flask (also from Ikea, in my case), then put the rest of the boiled kettle into the jug. Put the top on and you have great coffee which stays hot for several hours, if you can resist it that long.
I rinse the filters in cold water and reuse them several times so I'm still on my initial pack, and there are loads left.
Super easy to clean - remove the end and push out the coffee "puck" into the compost scraps or bin, then just give it a rinse under the tap.
Probably the most impressive piece of kit I've ever bought, for the price.
