Rated 2 out of 5 by from 2 months in and it’s glitching Started off brilliant , great price , done what was expected of it , worked great for an everyday use as an electrician... but after 2 months not it’s got some faults that keep occurring .. at times I place ONE probe on say an earth bar and it just bells .. says there’s continuity when obviously the other probe is not in contact with anything .. so no longer can be trusted to Bell things out .. can only be used as a voltage indicator now

Rated 5 out of 5 by from Great product Great product, I like the cap for the probes to protect them. The light is a nice handy touch to the product too. I’ve known many colleagues have this type tester for many years! Which is why I’ve given it 5 stars all around.

Rated 4 out of 5 by from A must have for the tool box Everyone who is working on electrics in any form should have one of these to hand. Great for belling out cables if you happen to come across a lighting circuit which has all been wired in 4 core then believe me this will save you a massive headache.

Rated 5 out of 5 by from Excellent, simple tester Great value tester, build quality feels good. Includes phase rotation which is a bonus and the torch is really handy for inside disboards. Glad I upgraded from the rubbish I had before.

Rated 4 out of 5 by from Nice! It works well, but i would have liked a case to store it in. Hence four stars only.
