The products of this company (HVMN) easily earn a 5-star rating... Although I've only had the chance to use 3 of the products, each of the products have been beneficial to my physical condition & my mental cognition. Being a senior citizen, I notice these sorts of things RIGHT AWAY! The customer service earns a 6-star rating. I consider their customer service to be "World Class Service"; and truly part of "the backbone" of this company. Any time I've had questions or concerns, the responses have been: * Personalized * Prompt * Professional * Above & Beyond Expectations It's a pleasure; doing business with H.V.M.N.
