A number of years ago I was a computer sales person. A coworker and I both sent in applications to a several companies to be computer product testers. We were both accepted, mostly based on the fact we sold computers.
There were a number of requirements to be a product tester that we both met.
We had to have full time jobs and a credit card. If we didn't test the products to their satisifaction we could be charged for it.
One was to test a new game controller. One of the requirements was to own a specific game. We had to be Internet enabled and load an program on our computers that would track our use of the controller. Once I hit a number of hours on the controller they sent me a review form. I gave a very honest and complete review of the product. They were impressed enough with me that the spread my name around and I was subsequently contacted by other computer accessory companies to test their products.
It all came to an end about 18 months later when I tested a game pad. Similar to a Super Nintendo controller. It was absolutely horrible. I reviewed it after 35 hours of use and gave a complete and honest opinion. Never heard from a company again to test more products.
