Bests & Worsts Reviews from Amazon

I want to write a review, but I don’t know what to say. It worked great until it almost burned down my house. The plug smoldered when the unit was plugged in but not turned on. I was so unnerved by this I looked at the box & the warnings & discovered this product is not rated by Underwriters Lab or any other fire-safety rating agency. I never even thought to check this because I took it for granted in the US. I don’t think this product should be sold in the US. I am extremely thankful I did not have a house fire-just a charred carpet
