I thought I had seen almost everything electronic, but a Harbor
Freight ad in this weeks junk advertising flyer had a super coupon for
a

"7.99 electronic fly swatter on sale with the coupon for only $2.49,
requires two D batteries (old separately)".

It looks like an oversize tennis or badminton racquet. Not a clue if
the batteries are hooked up to a grid to electrocute any fly that
crosses paths with the swatter, or if you get a shock if you miss the
fly, or whatever.

Does anyone know what this thing actually is supposed to do
"electronically"?
