Great Idea! Bad Product!
My son had RSV 2 times so I had to take his temperature regularly. I thought that this would be a great way to check it all day and throughout the night. It was always several degrees off. I emailed Vicks and they told me I must not be doing it properly. I read, reread and reread the directions and believe me, I did it just right and it did not work. This is a great idea, but not dependable at all.
