### ⭐⭐⭐⭐⭐ 







  
  
    Great for any diver
  

*by S***D on Reviewed in the United States 🇺🇸 on May 15, 2023*

This is a great product and loves that it conforms to my own individual mouth.  Made diving so much easier as I am not fighting to keep the mouthpiece in place.  Definitely recommend.

### ⭐⭐⭐⭐⭐ 







  
  
    Easy to custom fit
  

*by J***P on Reviewed in the United States 🇺🇸 on October 2, 2022*

Easily the best low-cost diving accessory, you don’t realize how tired your jaw gets until you don’t have to hold on anymore. Once you fit it to your teeth (boil and bite method) this thing stays in place with no effort at all and is so much more comfortable. Make sure you get the right size for your regulator, I’ve got a mix of brands so I ended up with a few different sizes.

### ⭐⭐⭐⭐ 







  
  
    Reduced fatigue, but maybe not best choice for frequent air-sharing.
  

*by S***N on Reviewed in the United States 🇺🇸 on January 8, 2017*

I've dove this for almost two years now. It was my first custom fit attempt, so it took me two tries to get the shape right. It does fit my mouth a little better than a standard mouthpiece so there is noticeable less jaw fatigue even after a 1-2 hour dive. It is definitely larger than I expected it to be. The material is firmer than the higher-end, soft silicone ones. There are two cons that I didn't consider: I do some tech diving and found that the material gets hard as a rock in cold water. It's not usually an issue since it's kept warm in your mouth, but when you do air-sharing exercises with your buddy and it comes out of your mouth for a while it's very noticeable. This leads to the second con: we practice donating the reg out of your mouth, and two buddies have commented that it felt weird fitting their mouth on "my" mouthpiece. I'm sure the cold/hard feeling didn't help. That said, in case of an actual emergency, I feel confident that most buddies would prefer an uncomfortable mouthpiece to their own air-less one.
