Rated 5 out of 5 by summerwedding from Solid- always a good buy Anyone who loves the seltzer water craze needs these in their life. What differentiates the ISI soda siphon is that you can make already flavored drinks fizzy. So I can make my fresh fruit juice for a cocktail and spritz it and ta-da- craft cocktail at your service. Also a great party display. The cartridges are so easy to use- perfect for holiday entertaining!Date published: 2017-12-11Rated 1 out of 5 by Erich617 from Might I suggest burning your money instead? I purchased an iSi soda syphon from Williams-Sonoma. I had trouble finding iSi brand CO2 cartridges for sale near me. I contacted iSi and was told that using any other brand would void my warrantee. I decided to order five sets of 10 cartridges to so that I would not have to continue ordering the cartridges. I used one successfully, and then my soda syphon began to malfunction. I cannot return the cartridges and have no use for them. In short, my entire experience with iSi, this product, and the syphon has been a tremendous waste of money.Date published: 2016-02-20
