I got this product so I could put tea tree oil in for my migraines and I will say the scent is very nice. It lasts for a very long time. The durability and capacity is amazing. I haven��t had any problems with this product ever since I got it. The auto shut off is all very nice since I don��t have to remember to turn it off.

I love how this product can go all day with efficient use. The settings are easy to operate and ambient is just the right tone.

This has lasted overnight. The lid, for replacing water and oil, comes off easy, unlike my other brand's diffusers. Controls are self-evident; Could use a little bit darker marks to indicate the levels of water to fill it with. Can be operated with the controls on the unit if you don't want to bother with the remote. Very pleased.
To answer someone's question, when you turn it on, then it beeps twice and shuts off, that means it is out of water.

This diffuser reminds me a lot of a cool vaporizer. It is plastic and light weight, with several hours capacity and remote control.

I love using this! It works so well and stays on for hours. It also has so many settings and will last a long time.
