・ The most outstanding benefit of having a properly fitted mouthpiece is less physical exertion is needed when using a second stage equipped with this mouthpiece, leaving the diver with significantly reduced fatigue

・ Simply immerse the mouthpiece (including all of its attachments to keep its profile in critical sections) into 95°C / 203°F water for 30 seconds, place it inside mouth, biting down and sucking on it for 30 seconds. Rinse with cold water and then recheck fit. Repeat the process as necessary
