Rated 1 out of 5 by Don't waste your money No grill as in the picture. I have had this fitted for 15 minutes and i want to rip it off the wall already. The noise from the shutter banging in the wind is REALLY annoying. Worst thing I have ever purchased from Screwfix. I love the shop but this lets your normal quality down. Don't touch it. 26 Jan 2016
Rated 3 out of 5 by Jury's out but so far so good. Bought two of these though neither had any 'Manrose' markings so not sure if they are the genuine articles. Made from quite thin ABS plastic and needs delicate handling as the lugs forming the hinge on the flap of one of them snapped off when the flap fell out of place as being dismantled ready for being installed. Remedied by a bit of Araldite and two panel pins! Installed easily and quickly and so far (I.e. one week and no gales) seem to work okay. Saw similar device in competitor's outlet which had Manrose label and noted it to be apparently thicker plastic though it was twice the price. If they continue to work as they are then seem good value. If they fail then cheap enough to discard and seek alternative. Screwfix service remains consistently good. 20 Dec 2015
Rated 5 out of 5 by Manrose Cowl vent Easy to fit good value for money.fitted over the existing holes no extra driling. 17 Dec 2015
Rated 5 out of 5 by Cowl doesn't make you scowl! I bought this as a replacement for the 14 year old one that had finally broken. It's well made and easy to fit. The fixing holes were in exactly the same position so no re-drilling. It looks good and does the job it has been bought for. You can't ask for more! 8 Dec 2015
