Review: 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.
Review: 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.
