Seems to be fine.
Wanting to replace two rubbish "Silavent" ceiling extractor fans with inline fans, I needed to source to vents with shutters, but none were available. So I bought two KAIR vents and two of these.They fit standard 4" (100mm) solid or flexible duct pipe.These are unsprung gravity flaps, so they need to be fitted nothing but vertically to operate properly. Fitted any other way and they won't close. They are also best fitted at the vent in the ceiling so they become dual purpose backdraught and odour eliminators.They seem good quality and due to them not having springs, there's nothing to go rusty and stop working.

Stops drafts
Very simple and effective. Time will tell of reliability and keeping the back drafts out.

Works well and easy to fit
I had 2 bathroom inline fans that allowed stronger winds to cool the bathrooms and create drafts. The backdraft shutters were very easy to install. The first fitted snugly over the fan spigot and the flexible hose was easy to secure to the other side of the shutter. The second fan spigot was the same diameter as the shutter so could only be butted up and secured with duck tape. Not ideal but functional and secure. The drafts have been considerably reduced and a good solution.

So much warmer
Our vent was left unfinished (long story), making it basically a giant hole to the great outdoors. This thing fixed the draft instantly and it’s SO much warmer now.I can’t comment on how it was to instal, but I definitely appreciate it

Works great but better with flexible pipe
Great easy way to avoid installing a new gravity or cowl vent. I thought it would push fit on the fan and rigid pipe at 100mm, however this is not the case as it’s exactly the same diameter as the duct pipe of 100mm. Therefore just used duct tape to join to a flexible pipe and it’s fine. Cut off half inch of insulation tape and taped to bottom of vent to stop any clanking noise and it’s prettyMuch silent. A bit pricey for a flimsy bit of plastic but it works

Works great. Noisy. Needs rubber strips.
Had to add rubber strips to stop it making a noise when closing. But otherwise works well.
