Best radiator key I have bought.
Even on a half rung nut had no problem. Key is tappered internally as the nut looked round in shape & tight but open with firm twist.

Brilliant
Essential for any household! Much better than trying to use a small coin or a screwdriver. This fitted my radiators perfectly, and it’s small size meant that I could access the valves really easily. I wish I’d only got one sooner! Fantastic.

Doesn't fit?
Id give it 5 stars but it doesn't work on my front door.

Okay
Does the job but feels quite flimsy, cheaply made, can’t go wrong for the price though.

Quick delivery and easy to use.
A replacement was needed for my daughters new house as the original lost in the move. As usual Amazon had the answer.
