I bought this unit a few weeks ago, came home, set it up & plugged it in. I moved it on the cupboard & for some reason it slipped and the top portion fell off onto the floor & broke a large chunk out of it. I was so upset as I didn't live near the place I purchased it. I contacted the company to see if I could possibly purchase just the top portion. Much to my surprise & happiness, the lovely, helpful representative located one & was having it shipped to me with no charge!! I picked this particular humidifier as it checked all the boxes for what I was looking for & now, thanks to this company, I can now get to enjoy it for years to come. I am so impressed and going back to purchase some for family members.
