I received the opportunity to test out the Soda Stream Source - it is an amazing product. You can choose the level of carbonation that you want, from light and bubbly to incredibly fizzy. There are also a ton of different flavours to choose from, we were given rootbeer, cola, and cranberry-raspberry flavoured water. I would like to try other flavours as well. This product is great for anyone who likes carbonated beverages combined with the convenience of making it 21st home - no more lugging cans or bottles home from the store. I also love the fact that there are no more cans and bottles to recycle!
