I am a magnet for bites of all kinds and carry topical and medicines with me at all times - so I figured this would be a good product to see if it really works. It arrived Monday and Tuesday morning I woke up with a bug bite on my arm... I used this little tool (3 x per the instructions) and documented with photos.- immediately after using, it stopped itching! And less than 24 hours later the bump / bite gone! There is a very faint red mark from using the thing but a small price to pay IMO. Bottom line: it’s awesome. I’m carrying it with me everywhere!
