I bought this for my boyfriends christmas stocking present and he loved it!
It came in very hand when during the summer we got a plague of flies in our house, everyday we were killing up to 20 each! As has been said in a previous review it does have a tendency to only stun larger flies so i then try to pick them up and fry them on the wires to ensure they aren't going to wake up again. You could also use a paper or large book to squish them once they have been stunned which is much easier than trying to squish a non-stunned fly.
Anyway, this is a great product and has come in very useful. Also, as far as i know we haven't changed the batteries in it, which is also very good to know.
