Easy to carry in the truck, and a life saver when I needed it. Easy to use, and a lifesaver on the road.

Does the job. Quality tool, but a little expensive for what it does. Does the job, but a little pricey for the DIY who only needs it occasionally.

Trailer maintenance with quality tools I used this tester and cleaning tools to eliminate problems pulling trailers of different makes and models within our fleet of trucks. Simple and robust tools that save a tremendous amount of time when we need to hookup and get rolling. It is a must for me and my fleet.

Absolutely LOVE this kit! Works!!! Could not be happier. Auto parts stores and RV stores don’t have this or anything close. Spent hours driving around town looking for a way to clean my rv plug because right turn signal wasn’t working and bulb was good. Had to leave on trip but ordered this for destination and it arrived on time. Cleaned contacts and applied ointment and it works! I now have a right turn signal!!! Yay!!! Thank you for making my return trip home safer and more relaxing!!!!

A MUST HAVE IF YOU HAVE A TOW HITCH–AN ABSOLUTE MUST HAVE!! This is a wonder tool-I have been looking for something like this for 5 years. It cleans the male and female ends of the flat spade style plugs VERY VERY WELL–it also does the round style. The tester is a must have it lets ONE person know if the turn signals work, 24/7 power plug is working, flashers working-everything but the brakes. that is a two person job because someone needs to push on the brakes. all the other things you just turn on (such as turn signal), walk back and look at the plug and you immediately know you have power at the plug. This tool is outstanding and was a monumental find since I have been looking for so long. The price was comparable to anywhere else on the web.
