Don't...
Just don't. I looked at this company and their machines a while back. They had a website (now gone), and youtube demos uploaded of the machine. It seems like a simple copy of an older Rainbow design the D4. Your best option is to get a refurbished Rainbow from a reputable store like Greatvacs (I'll link below). Or the Sirena, some members that swear by their Rainbows have them and seem to like them. However if you've had a Rainbow and liked it, best bet is to just go with another. They have the best support and parts availability of all the water machines.
