    Not as good as old fashion round type
  

*by A***E on Reviewed in the United Kingdom on 5 November 2021*

Worked ok but like my original round style ,cant think why these are made long and thin.But better than the N shaped double bubble type.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Smart Works well!
  

*by K***T on Reviewed in the United Kingdom on 21 May 2021*

This is indeed smart for few reasons; the air lock works well, even for rigorous fermentation. The smart airlocks lid keeps the mosquitoes and flies away as it is covered and the insects that are drawn towards CO2 that is being emitted stay away! Easy to Use and Clean!
