  • Great product

Works great, awesome service.

  • Works as advertised
Style: Bluetooth Remote Operation
I have just received the test kit and used it once. It works great and I was able too find the problem with my trailer wiring quickly. The Bluetooth feature is worth the extra cost. I simply drove my front axle up on ramps. I then was able to spin my rear wheels and use my phone to activate the electric brakes. One man operation. I highly recommend it. ... show more

  • Great tester, poor user manual
Style: Wireless Remote Control
I really like this tester with remote, but had trouble testing the brakes. tried it on three different trailers it tripped the overload on all three. The supplied manual has very sparse information is not very helpful. I was able to activate break magnets if the trailer was jacked up and I spun a wheel prior to pushing break button on remote, then it would stop the wheel without tripping the overload, don't forget to push the break button as soon as it stops the wheel to turn it off. ... show more
