Manrose Square Flap Vent White 100mm is rated 4.3 out of 5 by 47.
Rated 5 out of 5 by from Vent with flaps I've fitted a bunch of these outside on the end of kitchen and bathroom extractor fan ducts. They're easy to fit with 2-4 red plugs and inch 8 screws and a bit of silicon round outside. Flaps keep rain, draughts and insects out when fan not blowing. Good design and construction.

Rated 5 out of 5 by from Opens and closes! Looks neat and tidy after replacing a yellow stained one. Easy to fit and worth the money.

Rated 5 out of 5 by from Easy Easy to use and fix, if you use tape to hold open the vents during fixing even a complete DIY disaster like me can fix it.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
