Manrose Cowl Vent White 100 x 100mm is rated 4.2 out of 5 by 43.
Rated 3 out of 5 by from Not UV proof Does the job but after 6 Months has gone yellow in the sun. Needs a spring as the wind makes it flap about.

Rated 5 out of 5 by from Cowl vent for cooker expelair External plastics being renewed as is external walls. Excellent piece of plastic which would do the job perfectly except the workmen have not hung it straight so vent hangs open. Will be fine once they are back and straighten it.

Rated 4 out of 5 by from Check pins before installing This cowl design works better than the louvre type when it is windy, which is why I have just bought two more. However with one of the cowls, the two little plastic pins from which the flap is suspended were already broken. Screwfix promptly replaced the unit - thanks - but this part of the design seems under-engineered. For something that will normally be installed in an inaccessible place, I'd happily pay a bit more for something more robust.

Rated 5 out of 5 by from Replacement Bought to replace open louver vent. Wife constantly complaining about amount of dust coming into bathroom on windy days also draughty. Easy to install (Once I had googled how to remove front cover "Duh" ) seems to be working well no draught. No noise from the little flap and we live in a very windy area.

Rated 5 out of 5 by from Easy to fit and as described DIYers fitting our own kitchen, this was really easy to fit (once we've made the appropriate sized wall hole). Wish they did a black version as all our outer plastics are black, but it does the job just fine.

Rated 4 out of 5 by from No Draught and good value I've used this product on several vents and the cowling stops the wind from lifting the flap, unlike the vents with strip flaps. Keeps out the draught, easy to fit and good value.

Rated 5 out of 5 by from Excellent product A simple but great product works well and looks tidy.

Rated 3 out of 5 by from Needs redesign to strengthen. Multi-fit design good but difficult to fit tube as curved plastic locators for fixing the tube onto, as they bend even when lightly tightening cable ties. Have overcome problem by bracing the 2 larger curves with a thin stainless steel rod. The manufacturer could provide a cheap plastic rod that could brace the largest curves and locate in pre drilled holes.
