I received the SodaStream Fizzi to review. My family enjoys sparkling water in its own or flavoured so we really enjoyed this product. It was very easy to use and quick to set up. I feel the best thing about this machine is that it did not require any power source to be plugged it. It runs right off the the CO2 cartridge. This made it great for bringing outside, to camp, and made it very easy to pull out to make a quick bottle. It really did only take seconds to turn water into a carbonated beverage. Was very simple to use. My kids were able to make drink in seconds. You fill the bottle, put it to the soda machine for a few seconds, and done! It is definitely earth friendly for us as we were no longer purchasing cases of carbonated water and beverages, so all the packaging was not being brought into the house. The only downside I can think of is there is no indication or empty or full your CO2 tank is. But the tanks are fairly large. So if you kept a second one it would be an issue. And of course returning and recycling is a great option as well. I would definitely recommend this machine to anyone looking to get into making their own beverages and is looking for a low maintence, easily portable machine.
