The soda machine is my second and I must say that there is a marked improvement over the first four years that worked intensively (two bottles per day on average, approximately 3000 liters). The attachment system without screwing bottle works well to see if over time reliability is at the rendezvous, but I trust. The indication by the LED bubble level is very simple. The design is pretty nice with good quality plastics. I have three bottles still spawning in the refrigerator, if you think it's better equip you to purchase additional bottles. For CO2 refills are available everywhere (in store or online) Between 60 and 80 liters of sparkling water with a recharge according to your taste (more or less bubbly) syrups those of the brand are very good, but other brands work very well.
Only flat which cost him a star: the system to change the cartridge with the cap to be removed is less convenient than on my first machine.
No more heavy packs of water economy is the rendezvous and real.
