Have used Royal for several years and have been very happy with their FO.Their Calming, Energy, Relaxing, and Sensual Blends have all sold well and been very consistent from batch to batch. The Bergamot Italy & Mandarin Brazil, Riviera Sun, Romantic Blends, and especially Lemon Verbena, and Coco Mango are all great. I use C-3 with 2 percent BW. Each order is blended fresh as it comes in. This assures me of having very fresh scent every time. It takes several days longer, but it is worth it. Cari will send a list of scents that have been tested or recommended in Soy if you ask. Ron
