Rated 1 out of 5 by from I have had 2 of these, I had to take one back to replace as the LEDs had stopped working after only a week. My second one did exactly the same, different LEDs this time, I have not bothered taking it back

Rated 4 out of 5 by from All they do is flash the LEDs in sequence as it bells out the cable, nothing fancy. Mine works fine.

Rated 1 out of 5 by from Power button is hopeless Cheapish and cheerful....that is until you realise that the on off switch doesn't work properly and it has flattened yet another battery. I am giving up and going to try a different brand and design as this seems to be quite a generic design and everywhere you see it, it has bad reviews about the on/off switch.

The product appears as if it might physically split into two halves, so that one half can be connected to each end of a long installed cable. Is this the case?
