I got one yesterday and I'm now drinking my second cup of coffee made with it. I'm not sure it's a keeper yet, but it has potential. I'm using like you do, and as I'd be likely to do in a hotel room, using my filter/drip pot for hot water. It's about 170 degrees (175 is recommended). I really think the water needs to be hotter. Next cup will be with water heated on the stove just as a control for the experiment.

One trick that was immediately obvious to me when I opened the package is that it uses more coffee than what's the conventional formula. A "standard" coffee scoop is 2 tablespoons, which is officially recommended for a 6 oz cup. I usually use two scoops (4 tbsp) for an 8 oz cup. But two scoops with the Aeropress scoop is 6 tbsp. No wonder it brews a strong cup.
