Question about ISI Easy

I bought this water whirlpool. Since it is listed as a Kisag product, I logically ordered Kisag capsules with it. Well, I thought wrong. The water bubbler (at least the one I got) is from iSi, and the Kisag capsules don't fit because they have a different system (a plastic cap). Would Galaxus please be so kind and list product names and the manufacturer correctly? And please also - to avoid cases like mine - the matching accessories as well? Thank you!
