Question: I am considering buying a soda siphon. About how much soda will one cartridge make?
Document: The cost of soda water is not that much, but the hassel of going to the store to get it is gone. Now I just fill the jug with water and witha a co2 cartridge I have a liter of soda water NOW!!! !
Don't buy these! You can only fill the siphon 3/4 full of water with these chargers, or the siphon will spray water everywhere when you attemt to charge it. So you only get 3/4 of a liter of soda per cartridge, instead of the full liter you're supposed to get.
I bought this hoping it would fit in my Cornelius Keg CO2 Charger. After much trouble I was able to make it work but I would advise against it. These hold very little co2 and I ran through the box very quickly. Buy another product if you are trying to dispense beer through a soda keg charger.
I purchased these soda chargers for a Liss Soda Siphon, also purchased through Amazon. The siphon turned out to be defective; unable to hold pressure for 10 minutes much less overnight which was the latency period recommended by the manufacturer. This despite being a simple device with a straightforward instruction set which was followed to the letter. Bottom line: I returned the Siphon but Amazon states that because of the "hazardous" nature of the chargers they are unable to accept returns.
Well, at 79 cents per charger (which provides 1 liter of soda),  it works  out that it costs exactly twice as much as buying a 2 liter bottle of club soda from our local supermarket (80 cents). That ignores the $5.58 per pack of 10 shipping and handling charge.I called Isi to find a local retailer, and the customer service rep  promised me that 'Linens and Things' routinely stocked them.
I've been using ISI chargers for years. They work very well -- I've never had any issues with them at all. One charger is enough for one siphon of water. Water comes out crisp and tasty. I am totally addicted to it.One trick is to vigorously shake the siphon up and down after you've discharged the charger into it. This makes the water bubbly from the very beginning.Yes, using one siphon many times would be nice.
they make delicious water, are inexpensive and convenient to use.not much else to say, they have been around for years.
Not only do you need to check the shipping address when you start the order, you need to check the shipping address AGAIN if you make any changes (even payment method: I think that is what went wrong, I changed payment methods during checkout and it seems to have reverted to an old address). Aside from that, these are the gold standard in chargers... just be very, very, very careful with that shipping address, because it's strictly a one-way trip.
I'm slightly perplexed by the reviews which state the following:you don't get a litre of soda water (actually, that is true; you get nearly 2 ounces fewer than in a litre);I didn't know I could use this cartridge only once (how did you think that you could use a punctured, once-pressurized cO2 cartridge more than once???
This wasn't even close. The instructions literally tell you to SHAKE THE BOTTLE to make the soda. Yeah, guess what happens when you shake a bottle of soda and then try to dispense it?Please warn others not to waste their money. I am still hoping I get mine back but I doubt I will....
Answer: My syphon holds a quart - and uses one cartridge per fill
