Comments about Aqua Black Silicone Regulator Mouthpiece:

The material is very soft and comfortable. It is quite lightweight. When used with a lightweight regulator it works quite well. However, on heavier regulators it would cause discomfort and feel flimsy.

Comments about Aqua Black Silicone Regulator Mouthpiece:

The Aqua Regulator black Mouthpiece was easy to install, fits in large and small mouths, tastes fine, and breathes fine. However, it is soft and flimsy which means that it slips from my mouth and the Octopus Holder with Split Ring (The one that looks like a mouthpiece glove). There is even some jaw discomfort from biting down to hold it in place and it has slipped out of my mouth several times. A more firm material works much better.
