    • 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

    • WORKS GREAT
I bought this to replace a Hopkins brand in which the thin plastic cover for the "test" button completely deteriorated after just one season and rendered it useless, Hopkins will not respond to my request for warranty so I trashed it. No more Hopkins products for me. This item was easy to install, works quite well and given the side mounted test button (indirect sun exposure) will hopefully remain useful for years to come. NOTE: I will do an update if things should change ... show more

    • Good value/quality, but why no mounting hardware?
Product seems sturdy and high quality. However, the lack of mounting hardware is very annoying. There is conflicting info about if it's included. The picture says hardware is included then elsewhere it's not listed. Shame on me for not reading the reviews pointing this out.

    • I MUCH prefer THIS to the ORIGINAL manufacturer's kit!
I have a 2018 utility trailer, dual axle and electric brakes. It had been sitting for a few years, and I decided to rewire it and replace everything just to be on the safe side. Obviously, the battery for the break-away would be the FIRST to be replaced, but why not the entire system? The ORIGINAL breakaway, as well as much of the wiring in general, was, well, not to MY standards!! THIS, BUNKER Breakaway kit fit my needs AND standards!! This kit worked GREAT with the new junction box and round trailer connector replacing the NOT ALL THAT OLD but VERY BRITTLE and questionable wiring and connections! If you're pulling 6500lbs of ANYTHING!! ESPECIALLY with a smaller truck, YOU WANT TO BE SURE IT'S SAFE!!! I feel better with THIS breakaway kit than I did with the kit fitted from the manufacturer!! ... show more
