Atlas,
What I know about testing is not in question here. However, I feel you needt to know I majored in Mech. Engineering @ Gannon University. I spent countless hours in chem. & physics labs. But my background and knowledge of testing is not the question. Please, don't question my intelligence. Nuff said.

You have chossen not to believe what you watched. That's quite alright.
Manufacturer's know that they cannot convince everyone. I asked you a couple threads ago if you have ever tried SL. You have not.
Before you say that this product does not work I think you need to run your own field tests. You and I make assumptions ona product based on initial information.Our impressions are based on many factors. I've tried products that weren't worth a tinkers dam, but I made my own evaluation beforeIcondemmed it.
Make your own evaluation...try it out. If you still feel it doesn't work, send it back.
