Comments like this are always particularly frustrating to me, as it suggests that you did not actually read the article, and are now trying to prevent others from reading it based on your impression.

The company had a referral system in place such that 5 referrals meant the referrer obtained free LifeShield monitoring for life. Why would someone slant a review such that they could get a bad product for free?

It was much later that LifeShield announced a new program that gave $150 for each referral; this was a good while after the review of the product.
