This product is totally awesome!!!
I've tried a few different zapper rackets over the years, and none even come close to this one.
When you make contact with a fly it goes with hell of a CRACK! Sometimes they have even exploded. I have yet to make contact with a fly, moth or spider (yes, spider) that it hasn't killed in one, but be warned. If your going after a wasp, don't shock it and walk away or it may be you that gets the next shock! your gonna need to nail it a few times to kill it.
Apart from that this thing is perfect. I couldn't be without it. Great for pic nic's and BBQ's
