Title: Super Chargers
Review: Bought these in bulk for my iSi Soda Siphon.That brings the price down under 40 cents each.And they work perfectly (as with any cartridge, be sure the top is closed tightly).Charging for 40 cents is much more fun than paying 2 bucks a charge.And they are the only cartridges that I've found that state 'the CO2 used in this product is natural and does not contain any additives' and includes an analysis of the gas contents.A good deal - especially for heavy users.
