Manrose Cowl Vent Brown 140 x 140mm is rated 3.9 out of 5 by 35.
Rated 1 out of 5 by from Too noisy I thought this looked like a much detter solution than the louvred ones which always rattle, but I was wrong it doesn't rattle it bangs. I can't stand the noise it has to go.

Rated 5 out of 5 by from Good buy Needed a new vent to replace a louvre vent which let cold air into my bathroom. Price is excellent and quality seems to be fine. Now fitted cold draughts in my bathroom have now improved considerably.

Rated 3 out of 5 by from Manrose Cowl / Vent As advertised but did find this product brittle. Care should be taken when fitting, Not the fault of Screwfix.

Rated 5 out of 5 by from Does the job Replaced a multi flap version after one of the flaps disappeared. Easy to fit and quieter in the wind. Was suspicious that previous one was draughty and based on other comments expect improvement.

Rated 4 out of 5 by from Does what it says on the tin Useful design to suit rectangular and round outlets. Easy to fit.

Rated 2 out of 5 by from Noisy Rattle & Weak Hinge Like other reviewers: weak pins broke so used panel pin trick. Main problem is "banging" in wind, which was vetoed by management. Replaced with three louvre version, which still rattles but is far less noisy. Can't someone make a better cover?
