The REAL Cure for Cancer

This was worth it just to watch you mimick an MRI!

This is an intriguing topic. I appreciate your looking into this.

I would be careful of "free" trials of products. You make money from content and they make money off the product. Thus, you're paid indirectly from supporting products, whether the company pays you or not. That being said, as long as you make it clear that they came to you with an offer, it does make it somewhat understood. Where I find the line is crossed is when the whole program is about a product (e.g. "news" story) and it isn't obvious that it is merely an ad. As long as you do your due diligence and determine that it is more than a sham, then you're doing a service to your viewers.
