## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Expensive
  

*by N***E on Reviewed in the United States on October 28, 2020*

Good filters but too expensive.  I will continue to buy because they are the best I've found.  But I will continue to grumble about the cost.

### ⭐⭐⭐⭐⭐ 







  
  
    Good Value
  

*by O***A on Reviewed in the United States on December 10, 2020*

I have been using this filter for several years and have no problem with it.  My gold fish is now about 16 years old and if the filter is assisting him in his age...it is doing a great job.

### ⭐⭐⭐⭐ 







  
  
    Fit filter, require assembly
  

*by B***H on Reviewed in the United States on December 27, 2018*

They fit, I assume they're working, they do require assembly and I didn't find instructions so I checked online.  It's pretty straightforward and I didn't have any trouble getting them put together and into the filter.  The price is by far the best I found and totally worth the 60 second assembly with each change
