I have always been a large water drinker and as a consequence also drink a lot of canned club soda. I had been skeptical for quite some time about whether or not a SodaStream machine was worth the money. Now I can say absolutely I recommend! This machine could not be easier to use or more convenient. It encourages drinking water on a regular and every day basis, as it is always sitting on the counter waiting for you. The SodaStream bottle does an excellent job of keeping leftovers bubbly, even overnight and into the next day. I highly recommend this product to anyone who needs to increase their water intake. Let's be real. That's everyone. I especially recommend using it with lower sugar options, such as frozen fruit or water enhancers. I find that some of the flavours that came with my machine to try, i.e. gingerale are higher in sugar than I would typically like to drink (while grossly lower in sugar than other similar products on the market). No typical aftertaste, as found in purchased carbonated products. I found the instructions on this machine to be very vague. So the first week, we were seriously over carbonating the water. If the carbon dioxide switches are as easy as the instructions and website claim, SodaStream has made a new customer for life. I highly recommend.
