I am loving this diffuser! I have tried many other brands in the past, and the smell is great when you first open the packet, but usually fades quite quickly. I have this one in my bedroom and it smells like it's just newly opened everyday. I love walking into the zingy freshness this brings to my room, especially after a long day at work. If I had my way we'd have one in every room of the house! And the best bit... the level has hardly moved so I know I will be enjoying this uplifting treat for a long time to come!
