$220 vs $260 not exactly half.

And now where near as refined or neat on install.

HAYMAN REESE ELECTRIC BRAKE CONTROLLER REMOTE HEAD COMPACT IQ TRAILER CARAVAN | eBay

$155 remote mount and, I personally prefer the operation style.

With the Redarc you get proportional and full manual. I understand, but could be wrong, that to change from one to the other you have to stop the car.

With the Hayman you have proportional and a boost function instead of the manual control. What it does is increase the speed with which the controller responds, upto full manual, and can be adjusted whilst on the move.

I prefer it and have used both.

I've nothing against Redarc, I think they make good gear, its just that I think they are overpriced and other manufactures should be considered.

I have a tekonsha in the Defender that was previously in the D3. If you do not use the car regularly I would not recommend it as it tends to draw enoough current when asleep to flatten a battery after a couple of weeks. I had put it down to the air suspension on the D3 but it does the same thing on the Defer and there's not much else to blame it on
As a brake controller, however I can't fault it and its way better than the old non-proportional Redarc in my Falcon ute. As others have said on here if I was buying a new one I'd probably go with the Redarc proportional for neatness of installation but the display on the Tekonsha is useful as well as the availability of the boost settings to easily compensate for heavily loaded trailers. My main tow is a 3.25T ATM tandem trailer which can have a significant difference between empty and loaded.

Why doesn’t turning the dial on the Redarc do exactly the same thing? When my camper was fully loaded I used setting 4 then back to 3 on the way home when all the water and food etc was gone. What am I missing?

My biggest Redarc gripe is one of its features - it’s ability to be mounted in any direction simplifies install, but it’s need to re-learn when the battery is removed means my controller is a bit all over the place until it’s recalibrated - typically about a dozen stops. In my case this was quite a lot of distance and normally between trips I’d have taken the battery off to repair something. Minor gripe I admit

The settings on the Tekonsha are a boost to the speed at which the controller reaches full power, not an increase to the maximum power setting. it means that you can find a good maximum setting and leave it that way. I suppose though that you could just remember what setting you use for empty and full on the redarc. I'm just used to the Tekonsha and find it useful.

I have a Redarc in my MY13 D4. It was already fitted when I bought the car 4 years ago. I think it is not a Tow Pro and I notice that turning the knob allows proportional braking, but manually pressing is full braking. This is ok, but I would prefer proportional in both modes of operation. Some of the comments above suggest that this characteristic can be changed? Is this able to be changed on my older Redarc unit?

The unit on my Falcon ute is an older redarc and there is no motion sensor in the unit so it is unable to measure deceleration and increase or decease the voltage required. ie. no proportional braking just a fixed voltage determined by the position of the knob when the brakes are applied.
