Certified by who?
You use the products.. so who are you? How do we know you aren’t one of the company owners behind a user name?
Why do you have such a problem with someone wanting to test a product?
Here’s a little bit of advertising trivia for you… Remember the old commercials on TV for the “Pepsi Challenge”? Guess who started that challenge… NOPE not Pepsi. It was the makers of Coke that started them. They went to Pepsi and asked permission to do public taste tests between the two soft drinks. Pepsi jumped at it because it was free research and advertising. Turned out Coke put both feet in the doo doo though because their tests showed more people preferred Pepsi than Coke. So coke decided not to use filmed footage of the tests in their marketing. But Pepsi had a clause in the contract they signed to let coke do the tests that said Pepsi would get copies of the footage. The rest is history…
So again I ask… why all the problems with someone wanting to test the products?
