Review on Wacaco Nanopresso Portable Espresso Maker - Upgraded Version of Minipresso, 18 Bar Pressure Manual Coffee Maker - Travel Gadgets for Ground Coffee, Ideal for Camping by Brandon Whiteman

So far I'm really liking Nanopresso in general. I found it a bit contradictory when I sometimes get a perfectly extracted espresso with a creamy-brown crema. Sometimes the nozzle gets clogged and I can't get consistently good shots. I use a manual coffee grinder. Usually the only variable is the temperature of the water. It seems that hotter water leads to more clogs. I increased the grind hardness and after that the shot came out a bit under-extracted. I've started playing with grind settings, pump speed etc to get more consistent good results.
