Performance and User Experience
Applying heat to an insect bite has been proven to reduce swelling, especially when done immediately after the bite. The manufacturer claims the device is medically proven to work, and our testing confirmed noticeable relief.
The itch‑busting effect typically lasted a few hours, so for more irritating bites we needed multiple zaps throughout the day. For especially itchy bites, using the device before bedtime helped prevent sleep‑scratching.
