Confused

Why are there so many reviews starting with the formula wording " I received this product in return for my honest review". I don't understand. And why do they all leave really good reviews and lots of the reviews that don't start with that wording seem to have a more problematic tine with this product?

I buy this product regularly

I have fine hair and this works perfectly. Have been using it and the invite system for years.
