Rated 4 out of 5 by from Does what its supposed to! I prefer this style of vent to the ones that are slatted, they seem to rattle less when the wind gets up and look better. Easy to fit and does what is supposed to!

Rated 4 out of 5 by from Brrrrrr!! The North wind doth blow and we did have snow. So I bought one of these to stop it from blowing into my kitchen via the cooker hood extraction fan. Fair price for what you get. Case dismissed!

Rated 4 out of 5 by from Good looking vent cover I bought this to replace the same fitting I had fixed the week before because one of the hinge lugs snapped off the flap as I was fitting it it fell 12" onto the floor. So maybe not that robust but it works well & looks right in the brown color. I have to say the frame I had fitted 1 week previously the bottom part had warped with the heat of the dryer hot air However this did not prevent the new flap sealing or working so left that & just replaced the hinged flap easily.

Rated 1 out of 5 by from Poor design and poor quality This is very cheaply made with thin gauge plastic and thin easily broken pins. Worst of all the design of the draught proof flap is so light that any slight wind causes it to flap open and closed causing a persistent tap tap tap noise which drives you up the wall. The only plus point for this item is that it is cheap but I would happily pay a bit more for a well designed and well made item. Come on Screwfix you can do better than this.

Rated 5 out of 5 by from Excellent stylish product Bought this cowl to fit to the side of my shed to attach a tumble dryer hose to. It was simple to fit, strong and durable and looks good from the outside view of the shed. Great value for money and the ease of ordering online, paying via PayPal and collecting from store next day could not have been easier.
