Compared with other products, the magnet we use has a larger surface area, providing suitable magnetic force, which is stable and reliable, convenient to install and disassemble. It is not as difficult to take down as neodymium iron boron magnet

Bought it as a temp solution for backing up my trailer brake trailer using a 4 pin plug, and it was easy, cheap, and worked great!

Works great. I had one on my boat for several years and the sun eventually ate away the little strap. I bought several to keep them with the associated trailers.

We all have been frustrated with trying to back up the trailer when the breaks lock up on you. You then try and put the break lock key and it falls out by the time you get back in and put it in reverse. This thing works awesome and is so simple. You have to get one if you can relate to my frustration at all.

Bought a boat trailer that originally had trailer brakes but they were removed and the mechanism to engage the brakes was left to move freely. I found this very annoying at every stop light the trailer jostling about and pulling away jolted the truck to finally get moving. This fit in the slot pretty good but left a little room for some movement still. It was shipped super quick feels like it was made with good steel and painted orange to be visible if you used trailer breaks and needed to remove it to back up. It was a good deal and doesn’t look bad at all being in the trailer full time.

Like other users, I had a problem with the magnet chipping and breaking but it did do the job.

Without this or an electrical connection to the trailer brakes they lock up when backing up. This is a quick easy solution.

Works great. Better than the c-clamp I used before.

The key works well and the magnet insures it will not get lost! A good purchase!
