First of all, I don't want to comment on this product. This might work well for those who have used it. But I was able to use it for one winter. It stopped issuing mist about a couple of weeks ago. Unfortunately, it is not covered by Wayfair. So, no blame goes to them. I contacted the manufacturer and asked to repair it because it was on a 3-year warranty. However, they wanted me to insure the product and ship it to them in a 16inx16inx16in box. The total cost of the shipment came to about $50,00 to ship it to their repair department in the same state. This is what discourages most of the customers to return it for repairs. I paid a little over $100.00 and never want to ship it to them because I can easily buy another under $50.00. The 3-yr warranty on this is absolutely useless. I will not buy this product again.
