Manrose Cowl Vent White 100 x 100mm is rated 4.1 out of 5 by 54.
Rated 5 out of 5 by from Tumble dryer vent Required to replace old tumble dryer vent. Exactly same size. Easily fitted. The flap can rattle a little if the wind is in the wrong direction.

Rated 5 out of 5 by from vent cowl Do not let the low costs fool you. This vent did the job for me perfectly. Reliable and isn't rattly.

Rated 5 out of 5 by from Great cheap product Needed to replace a louvred vent - being face on to a park, constantly getting battered by the wind and very noisy. This is great - no issues with noise now. Simple to fix.

Rated 5 out of 5 by from A hole without a hole This is a good product for drier outlets or extractor fan outlets, it does occasional flap in high winds but nothing major - not like the louvre type which make noise all the time in wind . it is easy to fit and has an extra part which clips on to accept rectangle trunking. The cowl part stops any rain completely. Overall great product

Rated 4 out of 5 by from Decent but beware flap noise Decent (if not expensive for a bit of plastic). No grills on the bottom like the picture shows. I've fitted over 6 and found that in high winds the plastic flap can bang and make noise. In order to avoid this, stick a bit of small thickness foam or draft proofing foam (etc.) to the base where the bottom of the flap would hit. Some parts of it have ever so slightly discoloured from the white colour it should be.

Rated 2 out of 5 by from Cheap and flimsy I assumed based on the description and other reviews that this product would include flaps to prevent back drafts and insect intrusion, but it doesn’t. Despite the low price I expected a little better quality.

Rated 3 out of 5 by from Fits Round and Flat pipe Just to confirm - this fitting connects to 100mm round vent pipe or 110mm x 54mm flat vent pipe. Easy to fit - does the job but the flap (like all the flaps on these type of vents) is very light so the wind does lift it thereby allowing passage for air into/out of the vent pipe/building. I'm fitting a few of these so will be trying out various ideas to keep the flap closed but that does not inhibit it opening when the fan is in use. Most people won't bother but I'm very keep to reduce energy loss - it makes sense as it saves money and helps to reduce emissions that cause climate change.
