A Reliable Brake Control for Automotive Trailers

I recently purchased a brake control for my trailer from this brand, and it has exceeded my expectations. Automotive brake systems can be challenging to set up sometimes, but with this product, it was effortless to install and adjust. Through trial and error, I found that it responds well to my vehicle's braking system and works great on multiple trailer types. The only downside I found was that it took a bit of experimentation to find the right setting for my specific load. Overall, I highly…

Pros
  • Easy to install and adjust, works well on multiple trailer types
Cons
  • Takes a bit of experimentation to find the right setting for the load

Works but not as well as

I wish I had done more research before purchasing a time delay controller. This wasn't exactly the product I wanted so I will be back.

As with the reel above, the numbers only appear when the brake is pressed and adjusted at the same time. Also, the front handbrake slider was a little hard to press, then suddenly gave way and moved like I was looking…

Pros
  • VERSATILE proportional controller. You can use this electric trailer brake controller on almost any trailer with 1-4 axles (2 to 8 brakes). Compatible with low voltage, PWM, ABS, cruise control and electro-hydraulic control
Cons
  • Negative impression

easy to install and simple.

Amazing, I had to say that when I installed this controller. It was so easy to install. Quickly connects to the wiring harness adapter I bought from curt for my truck.

Inexpensive, but it has two main aspects: setting the gain of the brake controller and how hard you want the brakes to be. It has a digital display so you know what the output is. It comes with installation…

Pros
  • EASY SETUP. This electric brake controller connects quickly to your vehicle using a dedicated CURT wiring harness (sold separately). It comes with an adjustable mounting bracket and can be mounted at any angle
Cons
  • Unbelievable price
