If you're like me and love the taste of carbonated water, this is the perfect product for you. I don't, like most, like to add more waste to the trash. Let alone carting the heavy packages of plastic bottles. I personally use Britta filters to keep chlorinated gases to a minimum, but that's my city water issues. The unit is easy to use, takes up little space, and allows me to carbonate to my tastes. Lastly, after storing its 1 liter bottle in the refrigerator over night, the water retained it flavor and full carbonation.
