A totally proportional electric trailer brake control, the PrimusIQ is self-leveling so no level adjustment is necessary. Utilizing the primary sensor technology from Prodigy, the PrimusIQ now includes the Boost feature that gives users the ability to apply more initial trailer braking when towing heavier trailers. It works proportionally in reverse for backing into tough spots and includes a snap-in dash mounting clip and removable electrical connector that allows the unit to be quickly stored when not in use. You will appreciate the digital readout depicting a secure electrical connection, amount of voltage delivery to the trailer brakes and diagnostic features incorporated in the LED display.

After installing, set-up is simple; calibrate the braking pressure per the easy instructions, and you're set. This setting can be adjusted anytime as brakes age.
If your trailer is substantially heavy, choose one of the boost modes. In B1 mode, touching the brakes causes this unit to apply 13% braking immediately regardless of the feedback from the accelerometer. In B2 mode, 25% is applied immediately regardless of the accelerometer. So when descending hills, this enables me to select a mode where the trailer doesn't wait for the vehicle to start slowing before the brakes start being applied, and this helps to save the tow vehicle's brakes. I like to use B1 mode with my trailer when I'm descending hills. Other uses of the boost settings are to provide additional control when the trailer is heavy compared to the tow vehicle. B3, for example, is useful for trailers that weigh around 40% more than the tow vehicle, or beyond.
Inertia based controllers such as this one are so much better than the less expensive time-delay models. With a time-delay controller, the longer your foot is on the brake, the more pressure is applied to the trailer's brakes. Time-delay controllers are terrible for panic stops. But they're also terrible for longer gradual braking; they start out light, and increase force over time. This may not be what you would actually want to have happen. Imagine doing that on a wet road.
Inertia based controllers, on the other hand, brake proportionately to the change in momentum of the vehicle. If the vehicle slows more quickly, more force is applied to the trailer's brakes. So the rate of deceleration controls the braking force of the trailer. That is a much more accurate way to provide braking to the trailer than a "dumb" time delay method.
Now here's why I think this unit hits the sweet spot. Higher priced controllers work exactly the same way. There's no magic here. Higher priced proportionate controllers work just like this proportionate controller. They just offer more features. And most of those features are only useful for very specific tasks. Someone might pay $150 for a higher-end model, and never need or use the features that model provides beyond this one. Don't have 4-axles? Don't need to mount it at 90 degrees? Don't have hydraulic trailer brakes? Only have one trailer that you tow regularly? Then you won't benefit from a higher end controller.
On the other hand, if you drop below this one in features you typically either get time-delay, or proportionate but with more difficult calibration or no boost modes.
This model combines the features that 90% of us need, at a price that 90% of us would be happy to spend.

Nice adjustments, no surprises.
However, installing a brake controller is not a quick job, and requires confidence in running wires through the firewall of the vehicle, as well as routing wires to the back of the vehicle.
Not an easy install by any means.
