Hello
I have not installed any as I am a trouble shooter, and not in the States. They are paired with TKE controls.I personally do not like MRLs, but since they are here to stay, my appinion is that they are a very good and thus far quite reliable. The brakes are a little loud, aprox. 65 db at 3 feet. Working with the brake is quite easy and should be gaged and set up regularly.Hope this helps.
