I like that the cartridge is good for 64 litres of pop, no need to run and replace, some machines have cartridges for only 15 litres. Easy to use. Great for exploring possibilities for fresh fizzy drinks.

Bought this for my mum as she was fed up of carrying water bottles into the house from shopping. Seems okay but you have to carbonate the water a few times before it gets any real fizz into it.
