The AC-21-V Problue Silicone Mouthpiece comes in 6 different colours and is made of a durable yet soft silicone. It also features a bridge to cover the top mouth wall when biting on. This feature helps prevent divers from having a dry mouth while diving as much as possible.
Often, many brands with similar mouthpiece designs are less durable as they often get worn out easily and hence needs to be replaced frequently, resulting in high replacement costs. The Problue Silicone Mouthpiece on the other hand is more reliable due to its strength and durability in material.
The AC-21-V Problue Silicone Mouthpiece fits most of the second stages available in the market as the opening can be stretched.
