I bought and fitted these, the quarter turn valve on one of the radiator valves would not open or close and only let through a tiny amount of water. I had to drain the system to remove and return these. Screwfix were good enough to provide a replacement inhibitor for free recognising that the first lot I purchased went down the drain. I would suggest going with a traditional opening screw valve rather than a quarter turn one like this.
