After searching for a while I selected the Ellia diffuser range as it offers a variety of very aesthetic ceramic diffusers at different price points. I bought 2 different styles - the Ellia Relax and Ellia Refresh. Really happy with both. The Good Guys were the cheapest for the identical equivalent at other stores. Great customer service and assistance and $10store credit for your next purchase works well for then buying the oils of your choice. Most come with a 2 pack oil starter kit. Auto turn off function was a must for safety and peace of mind. Both units work really efficiently and look lovely.
