These do just what they are supposed to do, and are the best value I've found.

A box or two of these takes up much less space than the equivalent in bottles club soda or seltzer! A must have!

I got the soda syphon from the internet, too, but the cartridges were not offered. Luckily, cooking.com offers it, and I got ten boxes for starters. It's heavenly to make fresh seltzer water at home, much cheaper and easier, and better for the environment than buying from the supermarket, that's for sure. Now if I could just find out what to do with the empty cartridges? Anyways, try making your soda water at home, it will change your life. It's also very European, if that appeals to you (I'm from Hungary and am constantly looking into implementing our old-world practices into the "American Lifestyle"). Good Luck!

We have been using these cartridges for years and are more than<br>satisfied with the product.

Cooking.com supplied this product in four or five days, which is excellent service. I could not find the CO-2 cartridges locally.
