We always take our Nanopresso with us on trips and holidays. It makes a great espresso for such a tiny package. The downside was that it could only deliver a single shot of espresso at a time. You then had to clean the basket, dry the whole thing, refill and tamp the basket, reboil the water, etc. By the time the second shot was done, the first one had gone totally cold. The Barista Kit solves the "coffee for one" limitation by providing two double-shot baskets, 1 additional single-shot basket, an extension ring to make room for the double-shot basket, and a larger water container. The result is that I can now fill and tamp two baskets. I fill the water container with enough water for two coffees, press the first, replace the basket and press the second. We now have two freshly made espressos (single or double shots depending on the time of day) both nice and hot. Perfect for a globe-trotting couple like us.
Great product... we took it on an overseas trip and have a coffee ready by the morning before we started our day. Hope there is technology available one day the machine can also warm up milk without electricity. Overall, easy to clean and assemble, and took not much effort in the morning to squeeze out 4 cups of coffee that put a smile in everyone face!
