## Customer Reviews

### ⭐ 







  
  
    Poor quality. Purchased to replace older diffusers. They do not work.
  

*by J***O on Reviewed in the United States on November 5, 2020*

Tried all four but none of them allowed the CO2 to pass thru them let alone diffuse the gas. Have utilized others that "look" the same with my systems, which worked fine. These simply are poor quality.

everyone single one clogged within 2 days of use. waste of money!  Buy a steel oe designed for beer brewing instead!
