Mixer tap water-saving aerator with swivel nozzle. (New Town TN22)

Exactly as the title says.
This device screws into the end of the mixer tap in your sink, basin etc. Obviously, you need the end cap on your mixer tap to be capable of being unscrewed. It's a really useful way of reducing water use and being able to direct the water spray to all the corners of the sink.

Unfortunately, none of my taps have threaded ends so I can no longer use it.

I'm not setting a specific deadline but want this to be taken soon so it avoids ending up in landfill.
