Good machine to gasify its water for a very competitive price and even make sodas. The small display on the first received defective machine is of little interest, either on the level of gas in the cartridge or the level of gasification water.
Prefer a simpler and less expensive machines
In conclusion: the concept is very good, ca avoids water packs, it is environmentally friendly (less plastic to be recycled) and is cheaper than bottled water for use.
