Review: Well built, easy to place, and runs reliably - I bought this last year to add additional aeration to my pond, and it’s been running 24/7 since then with no issues. Right out of the box, everything looked well put together. The construction seems solid, and everything was the right length with no need to adjust or modify anything. One of the main reasons I chose this unit was the weighted base. My previous aerator required filling the base with gravel or setting up some kind of anchor, so having this one ready to go was a big plus. Another feature I really like is the two drilled holes in the base. They’re perfect for attaching a cable and small buoy. That makes it easy to retrieve the unit in deeper water without needing to dive for it. If those holes weren’t there, I would have added them myself. Pros: Solid construction and good quality control Weighted base, no need for extra anchoring Built-in holes for attaching a retrieval line Reliable, runs continuously without issues Cons: None in my experience Bottom line: Great diffuser that’s well thought out and easy to use. I would recommend it.
Review: Awesome Idea - Shipping really fast, easy to install, works really well with my windmill aerator.

*by V***N on July 29, 2023*

Shipping really fast, easy to install, works really well with my windmill aerator.

### ⭐⭐⭐⭐ Good till fitting broke
*by J***A on August 10, 2022*

I bought 3 of these aerators. Quality seam good till I noticed it wasn't bubbling correctly. Went to the hardware store and was able to use a 3/8" ID x 1/2" MIP brass fitting and a 3/4"MIP x1/2" FIP to replace the broken fitting. I no longer have a back flow stop but at least it's working again. Other than that the units work great.
