These are really strong magnets and there's a lot more in the box than I expected. I recently used 5-6 of these on a camping trip to attach a tarp to my car after it was raining heavily. They have held up great. Each magnet is about the size of a thick domino. I found a great use for them: During my hike, my aluminum windscreen (which I installed around my stove) was constantly getting blown away by the wind (the windscreen doesn't work). Right if you can't keep it installed! These magnets stuck to the metal plate through the aluminum shade and held it perfectly in place despite the wind. It was amazing! CONS: One started to splinter, broke in half and basically fell apart and it wasn't handled in any way.) But then again I got more than I expected and they will probably last a long time with constant use . The two parts still work fine so I can use that for smaller jobs. This isn't a huge downside, but I wanted to give a full and accurate review. I think you could probably drive them outside of your car on the freeway and they would stay where they are! I just keep them in my truck bed against the bed wall so they are ready to go when I need them.
