    • double sided tape???
Why the double sided tape? Makes the case HARD to get apart w/o tearing it up when it comes time to check/replace the battery.

    • Good kit, no hardware included
Very well built and easy to install. No hardware included so youll need some nuts and bolts and self tappers

    • Keep it dry
Everything seems to work ok. It's not sealed or water proof. I recommend sealing it or mount where it won't get wet.

    • Nice Piece of Equipment
Used on a feather lite stock trailer. Works well and easy to install. Also seems to hold up well to the weather in PA it has been in use and outside in all elements for about 2 years and still not a problem.

    • Functions perfect and easy to wire up and use
I added electric brakes to my 3500# trailer just for more comfort towing a SxS through the hills. I saw a review or 2 saying the battery isn’t replaceable on this thing. That is wrong. It is replaceable. However I believe you have to take the mounting screws off to get it open. And prying it open is a task. There are double sided tape foam pads keeping the battery in the space. So you have to overcome that glue/tape. But it will pop open then it’s a standard 12v breakaway battery like all the other ones. It functions perfect. I made sure to pull the pin and test that it applies the brakes. It does. I wish it had a coiled cable for the pin. I find I have to coil the cable up slightly and hold it together loosely with a zip tie so it isn’t dragging on the ground. But if the trailer did break away, it would slip through the zip tie then reach cable limit. ... show more
