I have 2 of the standard type Soda Streams; one in the house and one in the caravan. As a diabetic I find the soda water with a citrus much more refreshing than the traditional soft drinks. I grow my own tangellos, lemons and limes (as well as mandarins and cherries) which give me a quick refreshing drink when I want it. I usually go to the first ‘burp’, wait 10-20 seconds, a second quick burp and then done. I don’t really care if I am saving money but I do prefer to save the planet from an influx of plastic bottles.
