I got one of those too, Lidl I think.
Brutal thing it is.
Hell of a bang when an unsuspecting fly hits on it, it's game set and match.
Got a load of those citronella candles too but they don't seem to work, got bitten to death t'other evening and still suffering a week later.
I don't remember being bitten by flies when I was a kid, now it's a regular occurance
