Mosquito Bats

We should have mosquito killing contests. I am sure there are plenty of pros already. I know quite a few people who are adept at using the bats. They do it with passion. Some people can numb 10 in less than 10 mts. Then there are those who can even do it while sleeping. They keep the bat handy and swish about in the wee hours of the morning. There are a variety of bats avaliable in the market too with various options. Some come with an attached torch. Are these as popular in other parts of the world?
