I tried this product for free in exchange for my honest opinion. I wanted to get one of these for my babies room because it was said to help with sleeping. I'm so glad that I got to test out this product as it was something I wanted. I do have one but the one I have is old and harder to clean. I wanted to get a new one to start fresh with new baby. The assembly with this unit is super easy upon arrival. It even has a place to put your essential oil in if you want to. I really like that function alot. It's a nice big unit and looks sleek in design. It works whisper quiet and good for any room of the house. I love this machine.
