I have been buying the ISI Soda Chargers for several years and they have always worked 100%. This is a very good product. Amazon always ships them quickly!

Excellent product and service.No aftertaste (natural)Why four stars only?Lack of power in one cartridge.

These cartridges cost a little more than some other brands, but in my experience, they are worth it, because I cannot detect any unexplained taste. While the others provide very good pressure, they sometimes seem to leave an unpleasant taste.

The isi dispenser is very difficult to use, resulting in wasted, expensive cartridges. And even when they do work they make less than a quart. This is a total ripoff

I have an older soda siphon (the really nice expensive, glass, mesh covered one they still make today) and have been out of cartridges forever and finally decided to finally order some. These cartridges are just the tiniest bit too large and do not fit in the adapter to discharge...frustrating. I’ve had this issue before and it seems those sizes have perhaps shifted over the years. Have given up on the classic and just ordered a new, less snazzy model.
