Right. I've been using the Aeropress for about seven years. To this day I still use it every week, if not every day. I think the plunger is starting to go.
The point is it makes great coffee, and I've convinced many friends and family to buy one, but now I caution people that while it probably makes the best single serving coffee in a $25 package, it's not perfect. Basically there are a lot of parts and you're working the whole time you're using it. One guy at work accidentally punched the filter holder into the compost bin, lost forever.
If you're making 2+ servings very often, get a 6- or 8-cup Chemex. Much fewer parts. More: pour, stand around, repeat.
