It makes excellent coffee, without any coffee grounds passing into the body of the drink. It cleans very easily and is easy to assemble, while it can be easily placed on almost any cup. You don't need to have a paper filter, so one less accessory for those who travel or hike in the mountains, where every gram counts.

It is somewhat bulky, as it does not collapse, but the build quality is very good and it withstands impacts and mishandling.
