The NS Adaptor allows the Nanopresso to use NS CAPSULES* to prepare espresso. The advantage of using capsules is that the coffee is mechanically ground, measured, and tamped with a higher precision than we are capable of doing by hand. There is very little left for error, so your espresso is consistent every single time. Pods are convenient, mess free and easier to clean after use. *NS CAPSULES refers to Nespresso®** Original capsules and compatibles. Note that some non Original capsules might not work well with our machines. ** Third-party brand with no link to Wacaco Company Limited CHARACTERISTICS Dimension 66x62x62 mm 2.60x2.44x2.44 in Weight 130 g 0.29 lbs Remark NS Adapter can only be used on Nanopresso.
