After ordering the equipment, it took only one day to delivery through Amazon. Just great. After unpacking and commissioning of SodaStream device. Shape and appearance have a quality feel. The onset of the CO2 cartridge was not difficult. After about 6 weeks of use, the cartridge must be replaced. Spare there was in our supermarket for the price of 7.99 EUR. No more hauling of bulky and heavy water crates. Our tap water from the SodaStream tastes us better than before the bottled water purchased. The purchase is in our view only be recommended especially as the glass carafes, which we have added two pieces, for us are practical in use. There are now always filled four carafes in the refrigerator ready for use.
