this product is just a marketing gimmick, I have used it for a while, absolutely useless as it doesn't work at all, I have seen mosquitoes around it as if there was nothing, moreover the fragrance is strong and the refill finishes very fast but what's the use of it can't kill or fend them off, please don't buy and waste your money

The Refills do not fit into the Good Knight Gold Flash Machines properly, as they have manufacturing defect. Refill come off suddenly, fall down and the repellent oil gets wasted.
