Each package comes with the canister, a measuring tube and a twist-on siphon head complete with a pressure safety valve.

Buying them in bulk decreases the price. Each cartridge carbonates approximately four 8-ounce glasses.
How to Use
Using the device is quite simple. The iSi provides users with satisfactory sparkling water when the water is chilled before filling the siphon. It is also recommended to enhance the carbonation process by chilling the canister before filling.
Unscrew the siphon head and insert the measuring tube. Fill the unit with cold water. Replace the siphon head. Insert a CO2 cartridge into the cartridge holder and screw them onto the siphon head. At this point, the gas automatically enters the water. Shake the canister at least 20 times to ensure that the CO2 adequately disperses throughout and dissolves in the water. You then depress the handle to add carbonation to your favorite beverage. Or, pour the carbonated water into a glass and add the recommended amount of your favorite soda flavoring.
To refill this iSi Soda Siphon, you can use generic 8g CO2 cartridges. These can be bought in bulk on Amazon for roughly 40 cents a cartridge. Each cartridge is good enough to carbonate one bottle.
The compact size of the lightweight iSi Soda Siphon makes it easy to take the device anywhere. Pack it in an ice chest and enjoy sparkling drinks on picnics or in the yard during BBQs. The sturdy construction ensures that owners will have years of reliable service. You also save money by making your own beverages. Environmentally-conscious folks enjoy the fact that they are doing their part to save the planet by not adding to the accumulation of unnecessary trash.
Unlike many other soda maker machines, the iSi is manufactured in Austria, which means consumers get a better quality product. In fact, iSi provides a 2-year warranty on the device. The company also sells replacement parts when needed.
Overall, the iSi soda siphon is quite impressive as a soda siphon and is definitely one of the best ones available on the market. Its price is slightly on the high side but it often dips to the mid 50s which makes it quite affordable. It is solidly built out of metal and almost all users report that theirs functioned well and achieved good levels of carbonation. Thus, most people were satisfied with the iSi soda siphon. The only issues were rare and related to taste or leaking. Nonetheless, the soda siphon comes with a ceramic lining inside to preserve flavor. To sum it all up, this relatively affordable soda siphon fares quite well when compared to other similar products. Its metal construction means it’s very strongly built and it’ll be a long time before you have to buy another one. Also, the initial cost is compensated by its ability to use generic 8g CO2 cartridges which are much cheaper in the long run than most name brand ones (roughly $0.4/L compared to up to $1/L). The soda siphon also achieves good levels of carbonation, especially when used correctly. However, this process is quite lengthy especially when compared to soda machines.
What Others are Saying
Users enjoy the quality, the fact that you can use any type of 8g CO2 cartridges, it’s provenance from Austria, the level of carbonation when used correctly and the ease of use.
Users complained about how you need to use a specific method to obtain optimal carbonation (Use cold water, shake 20 times, wait before using). Some people mentioned that the water was taking on the flavor of plastic. The soda siphons of some users didn’t work and others were leaky. Also, some consumers reported that theirs broke or only produced flat water.
