IPA® Heavy Ranger® MUTT® 7-Way Round Heavy-Duty Commericial Trailer Tester | Portable, 7-Way Round Pin (SAE J560), For Commercial Tractor Trailers

Bought this to test trailer function on 7 way round pin connectors and works great...

Works well

just as described

fantastic product.

The product is poorly packaged from the manufacturer. The 7-way plug has an extended lip used to open the cover. The loose packaging allows the unit to shift around in the box and depending on how the box is handled it can break off. Another customer posted a picture of the exact damage I have. The tool itself is well put together and the quality is good. It works as designed. You’ll get a workout as you have to circle the trailer after each selection since it manually tests one circuit at a time. Keep in mind, you will have to get a battery and a 7-way cable to use this tool. A straight cable is a better option if you’re going to leave the tool on the ground while testing. Overall, including the damage, I’m happy with the purchase. I do feel like the manufacturer needs to add some foam to prevent damage but I’d definitely buy another one if need be.

Well made. Works as it should.

These are awesome!!

So i didnt really use a conventional battery i actually hooked it up to a Bauer battery, real lightweight , its plastic and im sure if you mistreat it , it will break but its really nice. I check trailer chassis and this makes it realll easy to check

tres bon pour mon utilisation que j'en ai a faire

It’s just right

Used it several times for yard checks and roadside and never let me down.

I am writing the review after using for couple of months. Here’s the crucks: 1. Plug and play, simple to use device( need to use both hands while plugging in) 2. With this much money, there should be an option for wireless remote controller to operate from a distance which could have saved more time as in my case 5 minutes is usual time to test 53’ trailer. Have to go back and forth to change function 3. Cyclic mode option would have been more beneficial if added, quick and would act as auto pre trip 4. More visual indicator like buzzer or LED flasher is also an added functionality for saving time and for quick troubleshooting Anyways, its nice to have it. It is pretty sturdy, look wise bit traditional but does the work

I use it to test trailer lights, love it
