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. Functionally, it's almost identical to 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'm selling it because the plan was delayed, and I bought a different manual product, and I didn't have as much space as I expected. The retail price is $899, and it cost $599 + $59 shipping + 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 hasn't been peeled off, and the condition is quite good. The box and all accessories are included. It has 24 built-in recipes, and you can finely adjust the amount of beans, water, and extraction temperature. It also has Wi-Fi functionality, allowing operation not only from the touch panel on the machine but also from your smartphone. It's the world's first machine that can froth both hot and cold milk with a single milk container. There's no need for troublesome switching; you can simply take it out of the refrigerator and set 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 found it more delicious than the De'Longhi entry-level machine I used to have. It has multiple automatic cleaning functions inherited from commercial machines, and basic descaling, as well as automatic cleaning of the pipes and milk container, are possible. (Citric acid can be used for descaling, dish soap for cleaning the milk container, and commercially available espresso machine cleaning tablets for cleaning the brewing unit) It is also confident in its durability, having passed 18,000 extraction tests. That's enough for over 10 years of use, even if you drink four times a day. Please note that the machine and app do not support Japanese. However, the on-screen instructions are basically animated, so you shouldn't have any trouble understanding the operation. I can also provide support if you have any questions. The warranty period is 3 years. I will handle any malfunctions during the period.
