If you think of this as an alternative to a cafetiere (french press), then you won't go far wrong. I keep it at work and find it quicker and less messy to use and clean than a small cafetiere. You do look a bit odd when using it!
A top tip is to leave the plunger in the tube, open it back to the line marked 4, stand it upside down, load the coffee grounds and water, stir, and only then fit the filter. Then turn the Aeropress over and press into your mug.
As with any coffee maker, the quality of your coffee has a massive impact!
