One of the worst kitchen gadgets I've ever had the misfortune to purchase. Thought that when they stopped working that perhaps it was the co2 canisters, so purchased additional.
Still no joy. Mine slowed down in the production of carbonated water until finally nothing at all happens when I try. Save yourself the time and expense and stay away from this product.
Retailers, both eTailers (Amazon) and bricks and mortar (Bed Bath & Beyond) should be more responsible about carrying new to market and or defective products. Manufacturers are very slow to correct deficiencies or offer any help with warranties and hide behind "user error"
