I have tested short cables and this tester works to verify continuity and correct wire on pins.

Nice little unit, well designed and manufactured. The top is tightly attached in rails, no chance of losing it. The pouch is a bit bigger than it needs to be, but does the job. I am glad I bought it, came in handy already.

It's working very well

Unit works fine. The instruction insert is poorly written though. I couldn't figure what they were trying to say on it. I just played with unit until I figured it out who to operate it..

A little pricier than some but worth every penny.
