A truly rewarding experience with Julie ahead of her game and open to the latest innovative and advance technology. She is not about the gimmick but is down to earth and is passionate about the practical and efficiency of her well researched products. A true innovator and pioneer who just cares for the wellbeing and satisfaction of her customers. Had the pleasure of speaking with her and was given top notch information about this item I was concerned about. More than happy I found their business. Love my purifying machine that emits negative ions to counter radiation from every devices and sterilise the air. I am ordering another diffuser from them, and sold out to their ethics and business model
