Query: What a waste of money

This thing is useless. I don't know what I was thinking.a.The thing is hard plastic, so you cannot swat on a hard surface.b.Like another reviewer said it will kill "one" bug in a swarm of bugs.c. It looks like a childrens toy, so it would be so easy for someone to pick it up - grip it - which activates it - and touch the grid.d. I think the draw for this device is - if you do kill a bug - it shocks the smitterines out of the bugs with a big spark - so if you are of that mentality (12 year old) then you will enjoy.But if you want to kill bugs- get the old fashion flyswatter.
