You press the pen tip on the -not aufgekratzten- mosquito stick and switched on the temperature.
It is hot and you have to sometimes even clench his teeth in pain. Duration about 6 sec. (2 hours selectable)
But fear not, the skin is not damaged and the pain and the itch is gone immediately. It really is true !!!!
Sometimes after using the pen of a mosquito bite was nothing more to see.
Currently however, the itching returns in the 8 stitches back after a few hours and then I repeat the application using the stylus.
It absolutely helps better than any cream or spray emergency aid.
But with young children I would with the application a little careful because it really burns.
