This referral hi-q keto program is included at no additional charge or fees and is optional to pursue. You do not have to refer others but if or when you refer someone, the company mails you a referral check. Frequently then, as you search the far corners of the internet, you will come across false information demonizing those who promote Enagic as being greedy or being scam artists simply because of this added benefit of being able to receive referral checks when an Enagic unit is sold.
