Liquid Image underwater Mask HD 320

I am always suspicious when they sell an HD pin hole cam. LiquidImage website gives a link to

When I make my own tests with the Liquid Image HD 320 underwater mask, it does not look great.

At first sight, it is bad quality:

-vertical bars

-noisy

-bad colors

-bad contrast

So I said to myself… that camera was build to perform in a blue environment in the ocean… not in a bathtub. In a few days I'll try it a pool… blue environment.

Did any one had a comparable experience?

I finally made the same test in a pool … and all the problems were gone.

-No noise

-No vertical bars

-Colors and contrasts… there is none in the bottom of a pool
