Unbelievable. It works. I am someone who suffers from the so itching from bites that I prefer bloody scratch swelling, than that I endure the itching. However, I am so far, spared luckily wound inflammation and want to avoid in the future that this is happening. Actually I wanted to purchase a heat pen sale, but discovered in finding this product. Since I was here whether the effect of the molecular breakdown of protein compounds or the poison by heat or current pulses and the divided opinions in the reviews quite skeptical, I decided on this expensive product and took the risk that it ends up in the garbage if impractical. But no. It works !!! It works ... I have pressed for about ten times. The itching was gone. I barely noticed the discharges. Half an hour later started since the day before receipt of the product received stitch again to itch. Spontaneous thirty-shocks staccato-pressure campaign freed me up to now (4hrs) of the annoying itching. Toll. Had I not believed. But perhaps it also depends on the type of Engraving and engraved. Anyway, I can only explain as the divided opinions of me. For me it'll work and that's a good thing.
