AeroPress

Used it on a camping trip last weekend and the compact size fit right in my backpack, no bulky equipment to haul. The clean cup it produces is noticeably smoother than my old drip maker, and cleanup took about ten seconds with the push-through press.

The whole brewing process is so quick and fuss-free that I've stopped using my drip machine entirely. The compact size means it lives in my carry-on now, and the smooth cup it produces is genuinely better than most cafes I've been to.

Bought this for my desk at work and it's become the best part of my mornings. The compact design fits right in my drawer, and pressing down a clean, rich cup takes less than two minutes.
