I have been using Melaleuca products for over 19 years and I do not have a single complaint about the company, the products or their integrity. My family was going to put me in assisted living until I started taking Melaleuca vitamins.
Their products are environmentally safe, more effective and less expensive. If you are not happy with a product, you get your money back. If you are not happy being a wholesale member, you can quit anytime and can even get your $19 membership fee back. You don't sell products or stock them.
It is not a multi-level company.
I have never met anyone who doesn't love the products and the company. I believe negative reviews are probably by people in competing companies as I have had incredible customer service every month, every year, always.
