Good and strong construction, works well, price is right

### ⭐⭐⭐⭐ Great, but needs adjustment
*by J***D on 23 August 2014*

I have moved into a new house and the bathroom fan has a 6" outlet with no cover, so the wind whistles through and makes the bathroom very cold (perfect for a room where you are guaranteed to be both naked and wet at the same time!). Bought one of these to stop the wind getting in. Perhaps my fan is a slightly different size or I should have bought something to connect the two pipes together, but unfortunately this grille is slightly too big for the fan pipe and blows off when the fan is turned on (quite comical to watch). Fortunately I bought some one inch Gorilla Tape , wrapped it around the outside of the fan pipe about four times and put this grille on creating a very tight fit. Came wrapped in a thin sheet of bubble wrap and a black plastic bag, wrapped with tape. Fortunately not destroyed by the Royal Mail monkeys at the sorting office. I now have a warm bathroom and am very happy.
