Need help with control, lift and steering? The NS Full Cheek helps tremendously with directional control. During turning the mouthpiece does not slide to the inside thus reducing friction across the mouth, promoting comfort. As the Waterford is flexible and bends in every direction it usually suits all types of mouth conformation, including big, fat tongues. This slimmer, innovative Waterford mouthpiece features our ergonomic LipSMART shelf which usually eradicates the previous common problem of rubs.
