Party Factory Universal 2x 16.6 oz soda cylinder for all standard soda makers, 450g carbon dioxide, CO2 cylinder for SodaStream

There are the least expensive cartridges I have found so far and they work great. I'm on my first charger so I'm still waiting to see how good it is with longevity (if there is any leakage) but so far so good. This will not fit the soda stream snap-in soda machines. This is a screw-in cartridge and should fit machines with that configuration.

There are pictures of 5 different soda machines and it say's fits all. All except "sodastream" is what it should of said. Why, because out of "all" the different soda machines I purchased the one that they don't work on. Why? Because sodastream has a different valve on the end of the bottle. They should now add the fact that it's "all" but sodastream on their advertisement. Now, I have to go through this email process to retrieve my money back. very unhappy

Not sure about longevity, still on my first cartridge. But these DO fit the screw-in type soda streams. Happy enough so far.

I like these they work like they're supposed to they're a little larger which means I get more and it still fits inside the ninja thirsty,

I bought these to replace my SodaStream cylinders. The neck on these is different and they don't fit.

They only fill about 1/3 the amount of seltzer. Going back to my regular brand
