Very good. Easy to fit, perfect for the job. Decent value.
It hasn’t made a difference for air lock & gurgling sounds. As soon as I remove it and flush toilet the noises all stop! Am I able to still return it for a refund?
works as it should good price simple installation great buy
Good product, easy to fit and solves problems with the building inspector
Only just fitted one of these for the first time so can’t attest to its reliability. Easy to fit and looks neat and tidy. Happy with it so far
Works well,fitted internally.No foul smells,so it's obviously working as it should.its been in a good few months now.Good value.Shame they don't do these in white.
Very useful and needed item and very easy to fit, allows airflow in and not out and stops any air-locking .
Product does what it says on the box. A little pricey for the item. So far so good.
Easy to install, stopped the smells we was getting.

This being a Macalpine product therefore consistently reliable did not disappoint

excellent product just what you would expect from McAlpine. good price
So easy to fit and use. Does exactly what it’s supposed to do and fits in seconds.
Very good product easy to fit and does what it's supposed to do
Very good product, lets you add/ extend soil pipe without having to install an airflow or intake pipe all the way to the roof.
Bought to replace an old air admittance valve. Fitted easily and is doing the job.
Very good - spring loaded you can hear it working, push fit very easy to install, no more smells.
