I have no experience with the product in question here, but I have no doubt there are many shill reviews on Amazon written by people paid by the product manufacturers to write such rave reviews.
Example: I bought a food product from Amazon that had no reviews yet but looked promising. The product I received was made with absolutely stale ingredients. Just awful. I posted a 1-star review simply stating my finding. Within a week there were five 5-star rave reviews posted for this same product, bringing the overall review over 4-stars. In the two months since then no new reviews have been posted. I can only think that the manufacturer saw their product called for what it is and sent in the clowns.
