I am starting to like the AeroPress a bit more. Just going a bit finer on the grind suddenly yielded much better results. Part of the fun with coffee, for me anyway, is the trial and error and the 'research' and experimenting. Even if the AeroPress doesn't become my favourite method of brewing coffee, I am glad I could give it a go and I will find some use for it.
I remember the inventor mentioning that the paddle should be used so that you don't scratch up the filter paper whilst stirring (or the plunger, I guess, if using the inverted method). The handle of the measurer probably works fine, although I have just spotted a large burr on the end of my one.
One thing I have noticed is that the process itself does not feel particularly smooth. For example, I often find myself unsure where to put my paddle down after the first stir, unsure where to put my filter cap, trying not to scald myself whilst rinsing and preheating the filter paper, dripping water everywhere, etc.
