Does the job - even better with a slight adjustment
I bought this because of the balanced twin flaps that will always open. I was not sure if others that have a single flap with offset pivot would reliably open and close fully.
Yes the spring is lightweight - but it is there to encourage the flaps to close, the backdraught will force them shut.
One of the flaps stuck a bit due to excess moulding on the pins. Easily solved with a knife as the flaps are easy to remove and replace as they flex. I did tweak the spring slightly at the same time to help them shut fully.
With a MF100S fan, there is plenty of airflow to open the flaps.Read full review

Flimsly and not fitt for purpose.
Fitted with only one spring when it should have two so the two half shutters can easily lay open in the rest position. The 100mm barrel is too short so attaching the two vent hose ends is exceedingly difficult to secure with tie wraps and keep the installation leak free. Not fit for purpose.Read full review

Works well !
I was put off a little by some reviews about the single spring .. but that seems to be sufficient when the fan goes out the flaps drop fine.the temperature of the small room immediately went up to be less draughty and I am delighted. I already had a manrose fan so it integrated well. Great 👌Read full review

Lightweight, good fit, effective product
It fits well, though it's a bit lightweight. It does have to deal with very low air pressure, so I guess that can't be avoided. Time will ell how well it lasts.

Spring not fitted correctly so not actually doing anything, but simple to rectify. Otherwise all good.

Back Draught Shutter
This is a good quality item, I was able to fit it in about 10 minutes. Should improve our heating in the kitchen which could get draughty when it was windy outside.

I've seen better quality coming out of a Christmas cracker. Non functioning spring allows the flaps to move without resistance which will cause them to rattle in the wind. Avoid.

Seems to work fine
Installed in a vertical lagged bathroom extract duct with the device near the exhaust. Operates fine probably helped by gravity... Just make sure (I did..) it is mounted the right way up!
