Rated 5 out of 5 by No need to get in a flap! Easy to fit (apart from getting & keeping the vent flaps open long enough to mark & fix!). Works as it should & lets air out, whilst stopping cold drafts. 20 Aug 2016

Rated 5 out of 5 by Works perfectly. Great price. Needed two of these. One as a replacement for our bathroom fan cover (the old one had lost one flap and the remaining flap had curled up) and one to cover an old vent hole (cheaper and easier than bricking it up!). Both went on fine, very easy to install (one screw in each corner). I also used sealant around the inside and outside edge to guarantee no water would get into the wall cavity. As previous reviewers have said, it has 3 flaps not 2 as pictured. Would work with both round and square holes. Took around 30 minutes to do both. 22 Mar 2016

I currently have a fixed vent that high winds suck the air from and sucks the internal flap open and causes the heat to be sucked from the room.
I also have a cooker hood fitted with flaps in the verticle position and a cowled vent on the outside wall and this suffers from the same problem.

Answer: 
Unfortunately all gravity grilles / backdraught shutters will be affected by external wind, as they have to be light enough to open when the fan is on.
