## Customer Reviews

### ⭐⭐⭐⭐⭐ Very nice, good quality product
*by W***S on 28 October 2024*

I fitted this at the gable end of a new build shed, aiming to alleviate the condensation inside the shed. The other end has a vent with a flap so it only opens when a breeze hits it. I just needed something to allow the breezes to enter to shift the still air on the most seen aspect, and this works really well, functionally of course but also aesthetically - this delivers in looks and would work nicely wherever it was sited, very pleasing to the eye.Before spotting this I had looked at two others both of which when their pictures were zoomed in they were clearly slightly imperfect copies of this one, but to a tatty standard, using inferior materials, and with a lower price, for good reason as we'd hope.This product is in a different league to those £5 cheaper ones.Many thanks.

### ⭐⭐⭐⭐⭐ This is the one to go for
*by W***? on 8 May 2023*

I've purchased and installed similar looking external ventilation cowls before, but this one had a couple of important features that sets it apart from the crowd — and also makes it worth a few extra pounds.Firstly, although not really a 'feature', it's easy to handle because it doesn't have razor sharp, poorly finished edges. A very similar looking model I'd previously fitted needed to be handled with gloves hands to prevent cuts from all those sharp metal burrs.The addition of the black rubber ring, that sits around the outer edge of the installed cowl. It serves a couple of important purposes:1) It creates a better weather/insect proof seal between the cowl and the wall (though I would also recommended adding a decent bead of sealant between the pipe and the recessed parts of this cowl to prevent anything that does sneak through from getting into the pipe);2) It limits the transmission of noise from outside to inside, especially the drumming of rain on its metal surface. Of course it's also a good idea to install a foam baffle inside the ventilation pipe if external noise leaching inside is a concern. Purpose made baffles can be bought on Amazon, though, it's pretty easy to make one from an off-cut of foam insulation board (use the same core drill used to make the hole through your wall to cut a piece of insulation. Poke some holes through the insulation to allow air to flow — the more/bigger the holes, the more air/noise — then install the insulation disc in place. Alternatively, cut a couple of discs, poke off-center holes into them then install them with the holes off-set, meaning that any noise coming through will not have a straight path to be transmitted but air will still flow freely).The main photo in the listing doesn't show it, but there's also a small drip guard included; a piece of metal designed to stop water from running off the cowl and down the wall beneath it. The only small criticism of the item I have is that there are no clear instructions showing how/where to actually install this part! I even went as far as writing to the manufacturers (who, sadly, failed to respond). However, a fellow Amazon customer recommended shoving it between the rubber seal and the wall (loosen the two screws holding the fuel to the wall, slot the drip guard between the rubber seal and the wall, gently re-tighten the screws, the pressure from the rubber ring will hold the drip guard in place).The attached photo shows mine installed — there's still a bit of a gap between the rubber seal and the (very uneven) wall, but I'll put a bead of black roof & gutter sealant around the edge to finish it off. Or, if you're skint/prefer it, a blob of sand/cement will also do the job.Again, unless you knew what you were looking for, this cowl would look almost indistinguishable from a cheaper version listed on Amazon. Having experienced installing both types, I would not hesitate from either recommending or purchasing another one of these Kair models.

well made, looks nice, we bought this for an Expelair vent because its metal and the plastic ones flap and are very noisy
