It’s fun and easy to use, it adds bubbly carbonation to almost any beverage. The iSi twist ‘n sparkle is affordable, small and compact so it takes up less space than the larger Soda Stream.
The only down fall is that you have to replace the CO2 cartridges with each use. They are not too pricey; $20 for a 24 pack.
Just fill the bottle with your favorite chilled beverage, then insert the sparkling wand and twist to carbonate. What ever you don’t use, just pop the top on and store in the fridge. I have found that IF I have any left, the carbonation can last up to about 3 days.
These would also make a fantastic gift.
