This is the top-of-the-line model from the SF1 series of "Kaxfree," a consumer brand launched by KALERM, a company that manufactures commercial fully automatic espresso machines. It has almost the same functionality as the "Eletta Explore," including the ability to brew cold brew, and I think the price-performance ratio is quite high. I purchased it by investing in a crowdfunding campaign for the global launch, but I am selling it because the plan was delayed and I bought another manual product, and I didn't have enough space to put it as it was larger than expected. The list price is $899, and it cost $599 + shipping $59 + 10% import consumption tax, totaling $724 when I invested. I tested it for about 3 days to check its operation. It has been cleaned. The film has not been peeled off, and the condition is quite good. The box and all accessories are included. It has 24 recipes, and you can finely adjust the amount of beans, water, and extraction temperature. It also has Wi-Fi functionality and can be operated not only from the touch panel on the main unit but also from your smartphone. It is the world's first machine that can froth both hot and cold milk with a single milk container. There is no need for troublesome switching, and you can use it simply by taking it out of the refrigerator and setting it up. Compared to De'Longhi's "Rivelia," which is also popular in Japan, and Philips products, which have a high global share, the extraction quality seems to be quite good. Please see the video for details. https://youtu.be/OotctBpQ9Fc Personally, I felt it was more delicious than the entry-level De'Longhi machine I used to have. It is equipped with multiple automatic cleaning functions inherited from commercial machines, and basic scale removal, pipe cleaning, and automatic cleaning of the milk container are also possible. (Citric acid can be used for scale removal, neutral kitchen detergent for milk container cleaning, and commercially available espresso machine cleaning tablets for the brewing unit cleaning) It is also confident in its durability and has passed 18,000 extraction tests. You can use it for over 10 years even if you drink it 4 times a day. Please note that the main unit and app do not support Japanese. However, the instructions on the screen are basically displayed in animation, so I don't think you will have trouble operating it. I can also provide support if you have any questions. The warranty period is 3 years. We will respond if it breaks down during the period.
