I don't think I have ever made it the "correct" way. I have had coffee from an aeropress made the way the instructions say, but that was stale preground coffee at my aunt's house when I didn't know I would be having coffee. My coffee (was buying Poison's coffee at the time) was less than 10 minute walk from me at my grandmother's house!
I will say that having one of those at the sink hot water sources was cool. My aunt drinks A LOT of tea and has a 190degree water source at the sink.
