## Customer Reviews

### ⭐⭐⭐⭐⭐ Bigger than I imaged
*by D***S on September 10, 2023*

Works great for my waterfall in my small pondEasy to clean as well

### ⭐⭐⭐⭐ Easy Pro is easy to clean
*by E***G on June 9, 2015*

Item was delivered very quickly. Just in time to install the filter over the weekend. Two things that I do not like. One: The filter cover is not included. This seller does not offer the cover for the filter which I was able to buy through a different retailer (not on amazon). Two: I wish it had some built in piping that I could hook up my intake piping on top, but still have it enter the filter on the bottom. I partially buried the filter and had to install some extra piping because I did not want the connections buried.Filter is working great. The pond has never looked cleaner/clearer. Cleaning is a snap. Just lift the filter bags and hose off.

### ⭐⭐⭐⭐⭐ Works
*by J***E on May 14, 2023*

It ended up being bigger than I had in my mind but it's a nice size for my application. It's very sturdy and will last a long time.
