Query: Lentek Biteshield RZ02 Electronic Racket Zapper

This product did not work at all. When we first got it, it zapped ONE fly to the ground, not killing it but stunning it momentarily so you may then kill it with a tissue. After that it never zapped again, the flies just flew into it and kept going. I would not suggest this product to anyone. We bought one last year from the super market and it worked all year, we just couldn't find them this year.
