Query: Not very effective, for me anyway

I bought it because we get bombarded by gnats every summer in South Georgia. I've used this thing for 3 days now, and with the gnats swarming around my face, I could only come in contact with a couple of them. I tried to swat regular flies, but never got a single one. The bug has to actually touch the electronic wire or it does no good. And believe me, getting the bug to touch the wire is not as easy as it sounds. I finally got tired of trying to swat things with this rather large and heavy racket thing and went back to good old bug spray. It's kind of like swinging a small tennis racket around and my arm got tired of that after several minutes.
