I am so very happy with the portable fly-screens that I got last week:
I have now solved a problem that is over two years old by finding appropriately sturdy, removable and effective fly blockers for my flat. With the actual summer weather we have been having here in the UK, this became a necessity, not a desire, as there was something odd about the light in my main/living room that seemed to attract a large group of the annoying, buzzing insects, who liked to fly around the room in circles. Hooray for (rather primitive) technology, as for approximately £50 I got three screens for the old-school sash windows in my living room, and can now enjoy the summer breezes without losing my sanity or needing to continually spray toxic poisons around my living space. Good for expat life? You betcha.
