My first Aeropress

Maybe it's to be expected... you get a new coffee toy, try it out, it takes rubbish. You try a few times more, watch a few youtube vids, and eventually it tastes good. Having tried my aeropress for the first time today, I'm still in the rubbish camp. I think, as usual, grind is the problem. Will try a few more settings, watch a few more vids, and cross fingers. Everyone says aeropress is great, so I'm not worried. And there's something vaguely satisfying about pressing down the plunger, even if the coffee ends up down the sink.
