Rated 4 out of 5 by Value for money Look's good and fixes easily. Should be robust providing you don't have to remove the cowl to often or the locating lugs may break. It's good that fixing holes are concealed but could be a bit wider apart to avoid interference with the vent hole (don't make the vent aperture too big). 16 Oct 2014
Rated 2 out of 5 by arrived broken unfortunately one of the hinge pins on the draught flap was broken. i've had this problem before as they're so small and flimsy 16 Aug 2014
Rated 5 out of 5 by Excellent value well made A great quality product which is excellent value and very robust. 4 Aug 2014
Rated 2 out of 5 by Earache inducing This is typical of its type. Built down to its low cost. They are designed to stop back-draughts and water ingress & do this generally well. Where they all fall down is the annoying rattle they produce during gusty weather, and if you have them fitted to your house and maybe the neighbours also do, the cacophony of rattling can be excruciating; especially at night. Unfortunately I dont think there is a quiet option made- what is required is a damping mechanism on the shutter flap hinge and not a useless bit of sponge which is stuck on some models which just produce more bounce of the shutter. 11 Feb 2014
