Mains Tester, Pen Electric Testers Screwdriver Electrical Tester Screwdriver 100-500V Voltage Electri c Testers Pen with Safety Insulated Handle for Checking Circuits, Fuses, Switches - Red

Careful what you poke with this.

The media could not be loaded. Used it almost daily and found that the tip, specially the flat side is tapered so it keeps on slipping. Another issue is the tip is not really locked secured in position… I knew one day it will be gone and this morning yes, found it’s gone… keeping it for current detection only… now it’s totally useless to me

Easy to hold.

I have try to test my screwdriver on any electronic or battery wire yet but I did use the screwdrivng work on any metal and wood and I like this one.

The tester works well but the screwdriver is not so good.

This is actually pretty decent, and better than expected. As an Electrical Engineer, I would have no issue using this. Quality is decent, and the shaft insulation strong and thick. Comfortable grip, rubberised handle makes this very practical in use.Unusually for this type of (tester) screwdriver, it has reversible shaft / tip, enabling slotted or Phillips / cross-head use. Upon completion of a circuit (ie touching the top with the tip touching a live (phase) terminal, the illumination is decent, and perfectly visible in daylight.Whilst for most situations it’s more practical and easier to use a ‘volt-stick’ (non-contact, proximity inductive tester), but for specific testing of terminals (accurately), this is a good and convenient alternative to a multimeter etc.Overall, pretty good. Decent quality, works well, no issues. Note this is for use within LV range only, and not ELV/SELV etc. Whilst LV (Low Voltage) is 50-1000 VAC, this is designated for between 100 -500 VAC range use, (which is fairly standard for this type of tool).I hope you have found this helpful.

For £ 7 it's worth £1.50 .rubbish.

It looks cheap and quality is poor
