Nice tester I work as a chassis mechanic and I have to deal with truck drivers on a daily basis. this tester is great way to find out if you 7 way has as bad circuit which will tell you where to start looking for the problem. This item will help you find out if your semi truck 7 way plug is bad or if the chassis that your are hauling has the problem . keep in mind it is always best to use a metering device for the best readings but if you can afford one of those metering devices this 7 way tester will do the trick . I would recommend this item to my fellow chassis mechanics to help do quick trouble shooting on 7 ways

Works like it should I’ve gone through about 4 of these freakin things. And every time I lost one I bought another from snapon like an idiot. This last time I bought it here from amazon. Best decision I made. Way less money and it’s the same exact tool.

Great product, well made, great quick diagnostic tool Great tool I use it all the time. tool helps you to quickly pin point whether there is a issue from the truck or trailer side of the lighting electrical system. Compared to my co-workers snap on version only obvious difference was a snap on logo and the significantly different pricing. Have had many truck drivers and other mechanics tell me they have never seen such a tool. Most of which say they are going to get one now. Have had it for a few months now and use it almost every day, so far it has held up. still looks brand new with no issues in functionality.
