Perfect for my needs
It was a perfect fit for 3 modern radiators in my house that I was struggling with. Initially I bought a 4 pack of 3d printed one ls which were a waste of filament. This is a great sturdy lump that does the job.

It’s a tap.
What can I say? It’s a tap! It turns my lock shield. It hasn’t fallen apart (and I bought it sometime ago) so I suppose it deserves full marks for that.

Not a lockshield key
Not for an old style lockshield radiator valve. This key has a square fit and not rectangular.

Ideal for Drayton lock shield radiator valves
Fits Drayton radiator lock shield valves. Can't grip the Drayton knob so remove screw & knob and use this instead. Perfect fit, much easier to turn.
