Title: Really frustrating failure
Review: Where the cartridges screws into the container, there is a tiny metal piece which punctures the cartridge and releases the gas, just like every dispenser. Around that metal is a annular piece of rubber, which I guess keeps the cartridge properly balanced so that the metal punctures the cartridge properly. Well, after only a couple of uses that piece of rubber ruptured, causing the disperser to mis-fire every single time I refill it, puncturing the cartridge without capturing any of the gas into the container, causing it to just start flowing out everywhere. Huge disappointment that the product can completely and utterly fail with such a small failure, now I'm stuck with a complete useless dispenser. Definitely need to try another brand that isn't this fragile...
