I have a floor-standing one in the bedroom, living room, kitchen, and home office, all whizzing around at supersonic speed for hour after hour!
I can't abide summer/sun/heat anyway, never could, but this particular wave is evil! Trying to lie on top of the duvet last night, sweating so much it was like I was swimming in it, being constantly buzzed by snotmonster flies - I absolutely hate them - they kept hitting my face and head, arms and legs, so I was forced to pull the duvet up to my chin, lie on my right side and put a pillow on the left side of my face.
I tried spraying the beasts with Raid, but for every 2 I kill, there's another 2000 to take their place! They were crawling on the bed, the pillow, and the duvet, too!
