Low Voltage Tester Klein Tools 69127 Review

I bought this unit to replace a cheap tool I bought a long time ago that has become unreliable. The Klein Tester is very high quality and durable. It looks like it's a tool for life.

Works, but the light is very dim. The probe was painted with non-conductive black paint. You must grind it down for the tester to work. A simple conductive coating would be much better.

The cable is too short. The lightbulb works intermittently. Since the wire contact is crappy. No secure alignment or pull-out protection. This is definitely a bench testing tool. Not for the field or anything else off the bench.

Delivered on time. Looks good but doesn't work right out of the box. To check I used another continuity tester on a multimeter. Top dollar for the usual quality but not this time. I bought a multimeter, it works fine too, but I left it for the tool box.

A complete pile of junk. I'm an electrician and have tested every part of this tester for continuity, but it doesn't work when everything is assembled. Also, the coating they use on the probe doesn't conduct current, which completely defeats the purpose of a continuity tester.

The product has already been used and the original packaging was sealed with tape. The item's lightbulb had burned out and I had to urgently look for a replacement. Evidence that the item was in use was the presence of a battery, although the original item did not have a battery. It works but was presented as new.

Here is a spring that is not attached to the bulb. Only under pressure did I have to work with it to get a good connection as the bulb went dim, bright, dim, bright. I finally got a good contact with him. I was expecting a bit more from Klein Tools as it was more expensive than other continuity testers, but the build quality isn't as good. However, it works.

Learn your lesson and stay away from test lights that aren't clear. Red is difficult to see when testing wires that can be damaged by a small current load. You can have 6 volts on a wire on a strand. It will glow, but you'll have to put your nose to it to see it. In normal use, it will glow normally. I just can't recommend it. Visibility is everything. You cannot diagnose what you cannot see.
