I bought the insect sting killer because my little daughter (4) is stung so bad and getting scratched up on's blood. Friends have recommended to us as a unit. I tried it on myself and hardly noticed effect because the stakes are usually "too late" is performed, in other words, when was already scratched. The problem is that the nightly mosquito attacks are usually noticed until the morning, namely when it itches and swells. I then attached the device and pressed properly. However, there was always unbearably hot before 5 seconds of treatment time were over. With my daughter I need that do not even try!
