In the past few years, we have covered plenty of fizzy water makers here. The sodastream Fizzi One Touch is also worth a look. It is a sparkling water maker that turns your tap water into sparkling water in seconds. It has 3 levels of carbonation for you to choose form.
You can use this to make 60L of sparkling water at home. This soda maker also comes with a 1 liter reusable carbonating bottle. You get 40ml bubly drops bottles in 6 flavors.
