The sodastream source is very nice looking. I especially like that it doesn't need to be plugged into an outlet! There are already many items taking up outlets, so it was great I didn't need to find one available for the sodastream. It took a few tries to get the hang of how the bottle is inserted so that water doesn't spray everywhere. Once I figured it out, it was super easy to use. I did find that no matter how many times I pressed down and held to carbonate the water, it just wasn't carbonated enough for me. I like my soda to be very carbonated, like commerical soda you buy at the grocery store. The flavours I got were gingerale, diet cola and cucumber lime. Out of all of them, I liked the gingerale the best. The diet cola had a strange after taste. Overall, I think this is a very cool niche product. I don't know how often I see myself using it. I like that it is environmentally conscious with the re-usable bottle. I wish the bottle could be washed in hot water or the dishwasher, so that I could ensure it's very clean after each use. I would definitely recommend this product for someone who enjoys carbonated water or soda regularly.
