Nice ítem
Work great on my project

Small and efficient
The diameter was slightly smaller than the bathroom extractor (both 100mm), so I adjusted it with many turns of sealing duct tape and it worked fine

Just ok
Served its purpose however has to be installed horizontally or springs will not keep damper doors closed

good -- just make sure you tape / seal it well!
it works for me, just make sure you tape it well! it's very delicate and technically not air-tight, but for the price, it's fine. I taped mine with aluminum tape and it worked just fine!

Waste of money!!!
The check valve flopped around inside the duct work and would have to secured with something such as glue. The springs are super weak and barely close the valve when the hinge pin is vertical if its horizontal forget it the top flap will stay open. Tried to glue mine in place and made a mess so in the trash it went!
