Non return valve for extractor fan

So far, seem OK. You need to silicone it into place to get a good seal. Not able to comment on how well it works as not been very windy at my location, but I get the feeling it will work well.

Great service

Product as described. Quick postage no issue

Good quality. Poor performance!

This non return valve seems to be well made. However, in the wind it clatters a lot, annoyingly! It is marginally better than the spring hinged type, but not much. It would have been better if the flaps were made of a softer material. It arrived on time, so no issues there!
