SodaStream 1 Liter Dishwasher-Safe Classic White Carbonating Bottle, 2 Count

The Soda Stream Bottles are 1 L each and there are two of them in the package. These are the official Soda Stream Bottles, so they certainly fit in the Soda Stream maker. They are dishwasher safe and it says “carbonating bottle”, which lead me to believe that there was something in the bottles to make the carbonation, however, that is not the case. These are just plain bottles – clear for most of the bottle and the bottoms and bottle caps are white. They have markings on them to indicate the water level and “dish-washer safe” and there is a warning on the bottle that says “To prevent personal injury NEVER wash in hot water over 150⁰F or place in freezer. ONLY carbonate water. NEVER use if damaged/deformed or after 04/2022. It also has a recycling symbol that states it is a “7”. I never knew that empty plastic bottles would or could have an expiration date. The packaging goes on to state that these bottles are “Compatible with Sparkling Water Makers” and goes on to indicate all of the makers brand names. They are BPA free and “Earth Friendly”. The BPA free and Earth Friendly things are seals. There is a third seal, but it is in foreign language. Anyway, These bottles are certainly made for carbonating water and/or making soda flavors. They are compatible with a number of different makers, which is a plus so that you don't have to buy a Soda Stream brand to use these bottles. Given all of this information, I would recommend them.
