Review on 🍾 Drinkmate Carbonation Bottles - Twin-Pack, 1L Size, Black Color by Johnny Weber

Hard to believe these bottles couldn't screw properly into my old model Sodastream. The threaded ends have burrs that appear to prevent the bottles from closing properly, leading to the release of water and CO2. I tried cutting them off but the bottom cap of the first bottle fell off before first use, the glue holding the cap in place was either applied incorrectly or not rated for normal fridge temperature. I have never had a problem with standard Sodastream bottles and will be purchasing the 0.5L OEM version after returning these items.
