Hello,
Looked at it quickly too and found this.

The Carbonator II is the second generation of the machine and launched in September 2018. Aesthetically it looks the same as the first generation, but our engineers have updated many internal components to make the machine even more robust and smoother. In addition, our packaging has been revised to make the machine safer during transport.

Therefore, I also think !!!! Is only the price !!!!

I have the Aarke Water Maker 1 and I am very enthusiastic about this device. No problems, easy handling, quick replacement of the CO2 bottle.
