This Review Title is Not anti-fog at all and the content is: Fogs constantly after first use. Stays in place well but fogs almost immediately. I tried warming it up by running warm water over it but nothing works to keep this mirror from fogging & it’s as far from the running water as I can put it in my shower which is about 30” away. Not impressed..There are other information for this review, one is This reviewer did purchase it and the other is 1 people think this review is helpful.
