Review title is I wanted to really love this diffuser [SEP] I wanted to really love this diffuser....I found that I  smelled it best by putting it on my night stand right next to me....any further away and I could not smell it. I like the changing colors...just wish there was a simple on off button...you have to keep clicking the button to turn unit off. I also wish I  could  have chosen which oil I received..as lavender  is not my favorite....I  had ordered blended  oils from another site and was anticipating aroma bliss...it works but you need to have it close to you. I may look for something  else and use this in my bathroom.
