Further to the £7 halfords cheap set that is now 1200 degrees heat.
These have a coating of rubber on the shaft & a moulded handled that keeps you safe from up to 1000 volts. If you are buying for a prezzie.... Get these.
You can use these plus they have the added bonus of you not get electrocuted should you put a screw into an electric circuit.
Throw the voltage tester in the bin. No pro would use it. They are not safe.- NO VOLTAGE TESTER OF THIS TYPE OF ANY MAKE IS SAFE
Do not work on live electrics with these. No sensible person would work on live electrics. These are for added safety. Which you do not get from the cheap Halfords set.
However the rest of them far out-value the Halfords set.
