I have used diffusers and essential oils for mant years (purchased from Doterra) and only recently found Lively Living and am so happy that I did. Thrilled to support a quality Australian company and the single oils and blends are so much cheaper than what I was paying. I purchased the Aroma-Home Diffuser 500ml and the Aroma-Haven 1.8ltr Humidifier Diffuser. The 1.8ltr I am using in my bedroom as the air was very dry as my husband has our air-conditioner cranking all year! The diffusers are both easy to use, and simple to refill. I was so happy with the quality of the few oils I first bought, that I ordered more to try, and they are all wonderful. Because the blends are so much cheaper that Doterra blends, it saves me making up my own blends which is great. The speed of the deliveries is amazing! Thanks Lively Living, you have a new loyal customer.
