## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great!
  

*by S***N on Reviewed in the United States on October 23, 2023*

Purchased for swapping between my 2nd stage reg and my FF mask without having to remove the hose with a wrench. Locking collar is a great idea to prevent accidental disconnects. Had to purchase 2nd male fitting, but worth the cost.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect for my Ocean Reef FFM
  

*by Z***C on Reviewed in the United States on September 21, 2022*

I have attached this to my Ocean Reef FFM and LP hose. works perfect and makes the mask much more easily friendly. I highly recommend for anyone who may regularly switch between regulators like I do. The pieces are very high quality, very easy to install and know how to use. They will last a long time if you take care of them and rinse them good after each dive.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars

*by S***N on Reviewed in the United States on September 19, 2024*

I have already used it on many dives and can confirm the high quality and reliability of this product!
