Cover
Item is made with heavy material and was delivered as promised

Lack luster.
Item worked as needed. Item started rusting before install was complete just being left out in the air. I had to clean it up and seal it with silicone before completing instal.

Dirty and misleading
The product has a sticky chemical substance all over it. It reeks of a chemical offgassing smell. The rubber seal that wraps around the inside ring was only partially installed, and didn’t fit the full ring circumference. The hinge is wobbly and cheaply manufactured. And worst of all, the items didn’t match the advertised pictures, which displayed screw holes where you could bolt the cover down. Overall, this product is terrible and frankly misleading in every way.

No locking mechanism
While the cover works well it has no locking mechanism to fasten the lid closed to prevent unauthorized opening.
