### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Water butt
  

*by M***E on Reviewed in the United Kingdom on 18 November 2022*

Nothing to dislike

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Seems to work ok. Not 6500 litre treatment
  

*by O***T on Reviewed in the United Kingdom on 17 June 2022*

Lack of rain during recent set spell has meant our harvested water is being used quickly. Product seems to work well, but the 6400 litre claim is a joke. 2000 tired maximum. Which makes it an expensive item for treatment.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Seems to make a difference
  

*by R***D on Reviewed in the United Kingdom on 10 October 2022*

This arrived quickly and is very easy to use. To be honest the scent of the product is only obvious when dispensing it, but the smell of the water in the water butt is noticeably less.Main tip - thoroughly clean out the water butt before using this product.Also regularly check the connector for leaves, moss, etc. which may slow the flow and increase the poor smell.
