“I only rate it 4 stars only because of the fact that I had paid for faster shipping and no one told me the diffuser was on back order. So I had to wait. I asked whoever emailed me about it later on if I could get my money back for that amount of shipping I paid and got no response. Still pretty irritated by it to the point where I kind of want to order another one but not order it at all either. I love the product and it’s purpose though.”
