Digital Mosquito Repeller Keychain

I tested this thoroughly prior to making this review.
As a British National, living in Northern Ontario by The Lakes, I am normally a prime target for being bitten.
Prior to purchasing this, my only other options was to spray myself in bug repellent, & smell of citronella & have greasy skin.
My first test, was cutting the grass in my bug infested garden.
First time ever, that I did not get bitten.
I then gave some to some construction workers, who were working out on remote islands with many bugs, who reported that they too are impressed with it.
Just incase it was a fluke, I ventured back out in to my garden without this device & received 3 bites within 5 minutes.
