Review: Just as described - Great product
Review: Look clear and work ok - I do like the clean look they give, and they do keep most of the water out and from flowing back in, but they ste bit 100%. They need to be installed completely vertical. Any angle at all and they don't stay sealed. Also they ate subject to debris. Even a small pine needle causes them to stay open.

### ⭐⭐⭐⭐⭐ Just as described

Great product

### ⭐⭐⭐⭐ Look clear and work ok
*by A***H on August 13, 2023*

I do like the clean look they give, and they do keep most of the water out and from flowing back in, but they ste bit 100%. They need to be installed completely vertical. Any angle at all and they don't stay sealed. Also they ate subject to debris. Even a small pine needle causes them to stay open.

### ⭐⭐⭐⭐⭐ They fit like factory.
*by A***R on September 22, 2023*

The service was next day and the fit was perfect. No having to drill new holes or replace the through hull fitting. Have not been tested yet but I can already tell the seal is really good on the flappers.
