They're fanf*ckingtastic! If there's ever a fly that annoys you, especially one of the big dirty arsed bluebottles, use this mofo on them and it will sizzle the living shíte out of them. You get a good crack and a flash and a tremendous feeling of self satisfaction.
And it's not cruel, whats cruel is the persistent buzzing that puts them in that situtation. Anyways, I always feed them to the spiders afterwards, circle of life etc
