Had a replacement for my old Wassermaxx sought who went irreparably broken. I actually wanted by the same company a new device, especially since I wanted to use for matching CO2 cylinder. But apparently the Wassermaxx is no longer manufactured, because I found it neither commercially nor the Internet. I therefore resorted to the competing product and have it so far no regrets. Beautiful are the water bottles made of glass, the optical (when guests arrive) make a better impression. Advantage of the smaller glass bottles: it can fit more into the refrigerator; Disadvantage: the 0.6 l not just large capacity, so you always 3-4 must have in use simultaneously. The device itself is simple and easy to operate and does the job. The carbon dioxide content can be metered readily from medium to "full throttle". For my purposes right.
