I have gotten a test product about every 9-10 months. You only pay for a membership (Yearly or Lifetime)you do not in no shape way or form pay for a test product. You have to fill out a paper form or online
form when you want to test. Once you complete a test you have to fill out the survey and return it. If you do not do this you will not be able to test again, part of the program.
Many people fail on this part or do not like the test product they receive and say to heck with it. After you complete your survey you have to fill out another test form also and join the list.

Wallhanr they no longer do this practice of sending stuff. Back in the late 1090's they did this to me also and I sent it back and attached a request not to be sent anything anymore.
As for testing I got to test some wildlife calling software where I would listen to a certain call (Deer example) then repeat it into a microphone on my computer and it would analyze it to see how well I did.
This worked great for turkey calling especially. This is just one example of many tests over the years. Some good , some so so.

To each his own,
