Aarke CO2 Refill Cylinder, Compatible with All Aarke Carbonator Soda Machines & Most Soda Machines, Makes Up to 120L of Carbonated Water (2-Pack)

They work as expected. Great value. Easy to replace and install.

The CO2 cylinder seems good. Works fine. It has the standard screw top that is compatible with my MySoda machine.

Excellent quality. Good service. Easy to use. The initial expense (for the Aarke Carbonator 3) is worth it in the long run. If you have tap water that has a good filter (reverse osmosis filter), and you zap it with the CO2, then when it's in a glass, sprinkle in a little non-refined salt (like Himalayan or better yet Maldon salt), voilà!--You get clean, excellent tasting mineral water. Plus, we no longer need to lug bottles of water into the house or worry about plastics which are present in all commercial mineral waters (e.g., Gerolsteiner, San Pelegrino, both of which we used to drink).

These work great. But now I need to find a way to return the empty canisters.

Good product, however, I now need to return the canisters and order new ones and there is no indication on how to do this on Amazon.

Thee canisters work the best with the Aarke carbonator 3. I absolutely love fresh seltzer! Better than the cans any day

Very happy with product.

Easy to use product. No issues. Lasts a good while even with all the carbonated water my wife makes (several bottles a day). We bought a total of 3 bottles. They have a refill process that lets us send in the used bottles (two at a time) and auto-ship us new bottles as soon as USPS scans the label.
