Custom Fit Guaranteed FIT Mouth Piece for Scuba Diving and Snorkeling Snorkel Dive Divers Semi-Dry Dry Snorkels Authorized Dealer Full Warranty

These are wonderful as they completely alleviate mouth fatigue while scuba diving.

I've been using one of these for over ten years. When I upgraded to a new regulator, had to get a new mouthpiece because the mounts aren't universal. Shipping was prompt and it fits perfectly. I'm looking forward to another ten years on this one.

The mouthpiece met all expectations. I usually have jaw fatigue after my first couple dives, if I haven't been in the water in a while. I just dove two weekends after not diving for about a month. No fatigue.Just be sure and look at the list to find the model that is correct for your regulator. I ordered this clear one incorrectly the first time.

According to my son who is a dentist, I have a torus palatinus (and he inherited it from me). This means that a regular mouth piece irritates my gums because of a protrusion in the roof of my mouth, and after a few dives can be very painful to my gums.If you find that when your dentist takes X-rays that holding the sensor in your mouth is painful, you may also find a regular mouthpiece on your regulator becomes painful as you do repeated dives.This mouth piece the ideal solution to my problem. At first, it seemed I was swallowing too much sea water, but after a few dives I was able to relax and not bite on it as much.

Super easy to set up and works great while diving.

Poorly Made(AWS)

Works just like a mouth-guard that is able to be molded. It reduced my jaw fatigue and is well worth the cost.

Gets lots of use and is perfect for older divers with dentures.
