Rated 3 out of 5 by from Beware the odd oval hole I had already set up the fan from the bathroom with 100mm flexible ducting. Bought this for the roof. It is not clear that the unit comes with a rather weird, large oval male connector for the ducting. Unfortunately, the vent was exactly what I needed so I had to buy some 150mm flexible ducting (not available at Screwfix), a 150mm to 120mm adaptor and a 125mm to 100mm adaptor (not available at Screwfix) to be able to use my 100mm tube that had been previously placed. It also took some ingenuity, cable ties and some self tapping screws and washers to secure a round 150mm tube to an oval hole. All in all a bit fiddly.

Rated 3 out of 5 by from Frustrating. I read all the reviews, and understood that the odd shape of the hose attachment at the back had been an issue for people, some also pointed out that I would need to buy the specific hose for this product which isn't really made clear. So I went ahead and bought both items, still not a bad price for both, but the issue is definitely that stupid oval shaped hose attachment at the back, even with the purpose made hose, it was still not making a satisfactory connection, I covered everything in foil duct tape which did the job. I couldn't find any pics on the internet showing the reverse side, I took a pic of mine but can't add it to my review.

Rated 4 out of 5 by from Design flaw Excellent product..easy to install, but if connecting to extraction you'll need a oval to round connector. Why this is made to oval is utterly stupid, but it does give the manufacturer another product to sell !!!!

connection to circular ducting

How does this vented slate connect to the circular ducting as at the rear of the vented slate is elliptical (oval) in shape and the flexible ducting is circular is there a particular fitting required?
