One of my best investments! I bought one for myself and one for the nurse's office. When my first graders complain of an itch from a bite, I show it to them and demonstrate on their hand what it feels like. I, then ask if they want me to use it to take away the itch. After the first use, they come to me daily with their new bites. It only takes one time to eliminate the itch and saves loss of instructional time because they are not having to leave the room to have itch cream applied multiple times a day. They love it as much as I do.
