As I get older mosquito bites are becoming a real problem. I hate bug spray but forced to use it constantly. If you use this shortly after you discover your itching from a bite 8 times out of 10 it should work. 

Prevents the bite from going further and never bothering you again or at least diminishes the itch so much that it’s not a problem anymore. Leaves a ring that disappears quick enough on your skin.

I keep it in my bag and feel happy to be able to help myself should I get a bite. Not hard to use and may give you relief. Worth checking out. It’s an ok price. I will see how long this gadget lasts.
