Well that never worked for me...the flies always got wise to the thing. I found it clumsy to use and quickly reverted to the cheap and very lightweight plastic swatter. Believe me WyreNut, there's pleny of aerobic action when my swatter comes out. I have even managed to swat flies in mid-air. My Mrs worries about me, especially when I venture outside and begin the genocide...they just keep coming you know.
