Which style of Brake Controller is best?

I have a Prodigy, it works in reverse! some don't.

Cheers,

Here's the difference.
Some you dial up how much brake force you want as in a certain one with a remote head.
It applies the brakes according to that regardless of your speed or rate of deceleration.

A Prodigy or a P3 are a proportional controller.

That means the harder you brake the more pressure it applies to the van brakes.
It also means if you are applying them lightly when rolling up to lights they wont lock the brakes as will the other type if set too hard.

Its a no brainer really

Had a Prodigy for 3 years and no probs whatever. No lockups either

I used a prodigy on my Patrol and it worked really well. I took it out when I traded the car in on a Prado but then couldn't fit it into the Prado. It is sitting in my shed now doing nothing!

To answer the OP's orginal questions.
There are 3 basis types of electic brake controllers.
'Solid state' - Redarc, Hayman Reese etc.
'Pendulum' - Teknosha Voyager - Hayse Lemmerz, Kelsey etc.
'Proportional' New generation Hayes G2, XPS, Tekonsha Primus IQ and HR Guardian IQ.
Then there are the top of the range 'Proportional' controllers, the Tekonsha Prodigy P2 and the latest P3 with more diagnostic features.
The proprtional are true 'Set and Forget' controllers with the Prodigy models being my personal choice over all others.
