Handpresso - the only good handheld espresso rig. Includes their portafilter upgrade.
Barely used - brought on two camping trips. Works perfectly, and produces actual proper 16-bar viscous espresso, even if you use one of the "ESE pods," provided they're fresh.
Comes with everything (unit, display box, ESE pod adapter, spare gasket, manual) and also their "intense" portafilter upgrade - fewer holes, longer infusion time. You could just throw the stock one away. The "wild hybrid" kit they sell currently is a normal set with one of these.
Fits in a bag, cleans up easy, made of cast aluminium with steel fittings.
