i liked this diffuser so much it is definitely in my top 5 diffusers. if you're like me you like the health benefits diffusers bring whether its relaxing or moisture this homedics diffuser brings even more with calming sleep sounds which help me sleep better and it also has an alarm which is super cool especially the ability to dim the lights is cool because I don't like any lights while I sleep. bottom line I don't have any complaints at all I just want to get the word out of how great this product is and I wish they could make more products like this one. definitely one for the collect I will buy another one just because I like it so much and want people to know that if you're thinking about buying it don't hesitate
