I have been using the Patriot for a few years. Went with it because it did not require any mods to the toad. After about four years, I had some issues with it not wanting to set up properly. After some discussion with Blueox on the phone, found the internal battery was kaput. Factory only replacement. Since we were on our way to Alaska, BO agreed to send me a new assembly to our next stop, prepaid, for about 1/3 the cost of a new one and I return the old one, prepaid to the factory.
The new unit has some changes to the claw making it easier to attach to the brake pedal and new software. Overall, it is a much better unit than my original which I had for about four years.
I have not had any issues with it applying the brakes on steep grades and since we live in BC, there are more than enough steep grades to contend with. I leave it on the default setting of five and find it works as advertised.
Takes about two minutes to set up or disconnect. I store it in one of my basement cabinets when not installed along with my plastic bucket of cables, pins etc for hook up. Would I buy it again? Short answer, Yes.
