Are you the type of person that needs their daily espresso? Well, Mypressi TWIST could be the gadget for you. TWIST uses fresh ground coffee and requires no pumping, priming or compressing to make a shot of espresso. All you need to provide is a standard N2O cartridge (the kind you use in whipping cream dispensers), hot water and ground coffee. Then just press the button to push the hot water through the coffee. The cartridge can be used approximately 8 single or 4 double shots. This is great for camping!
