## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great Product
  

*by L***E on Reviewed in the United States on November 30, 2017*

Does its job. Bought this for the living room as it covers pretty big area, and almost noiseless. It's obvious when you need a refill as the LED light turns red when there is no water. I like their smart feature which adjust the mist based on humidity level, save energy and water tank last longer.

### ⭐⭐⭐⭐⭐ 







  
  
    Works great so far
  

*by S***Y on Reviewed in the United States on April 12, 2019*

Bought this to use in the bedroom.  Needed more humidity.  Just be careful where you place it since the mist will fall on the surface. The directions warn you of this.

### ⭐ 







  
  
    It stop working in 7 months and no response from manufacturer - The warranty is not real
  

*by M***O on Reviewed in the United States on August 6, 2019*

The humidifier is nice but the statement "1 Year Manufacturer Warranty" is not true. The one I bought in January stopped working in July and I emailed the manufacturer (service@roolen.co) two weeks ago and no response. A pity this is a false description of a potentially good product.
