This stuff works! Mosquitoes seem to love me and my son so I have to keep bug guard in stock in the summer. One day we went fishing and I sprayed it on my hands to rub on my son and I rubbed the excess off my hands wiping down my legs. I wanted to get some sun on my pale legs, later that evening someone pointed out my legs. They got sunburned except the finger streaks where I rubbed off the SPF bug guard lol, was embarrassing but it proved how well the product worked! A+
