DIYMAG Powerful Neodymium Bar Magnets, Heavy Duty Magnets with Double-Sided Adhesive, Rare Earth Magnet Perfect for Fridge, DIY, Garage, Kitchen, Science, Craft, Office-60x10x3mm, 12 Pack

Functionality is great. neodynium is strong, no issues with cracking with frequent use. Size was exactly what I needed and was as described. Adhesive strength could be better, I prepped surfaces perfectly and the adhesive gave away somewhat easily with the heat of the sun.

Why did you pick this product vs others?:These are powerful! Hard to separate, so they are very good under wood and leather!

The adhesive is not as strong as the magnet but the magnets are great. I use them to help hold the rain fly on my jeep and they do well.

I found that one of my latches had failed, causing the 20"/30" ceiling mount filter door to sag, and noticed another worn down considerably. I found a YouTube video describing how one man repaired his door latch using these Neodymium magnets. I tried this out, but could not get the two surfaces to close completely. I rewatched the video and found he used 5mm thick magnets, while these are 3mm thick. My workaround was to double them up (one on top of another), giving me probably 7mm thickness between the door and the top of the magnets. I used this double configuration on the short edge (where the breakage occurred), and two more on the non-hinge long edge, spaced in thirds (one at the 1/3 area, the other at the 2/3 area). By doing this, I was able to get the door to close together and hold without the latches being engaged. For safety I went ahead and latched them when I was satisfied with the repair.For transparency, I also bought these type of magnets in a round configuration, with a countersunk hole in the center. Using a 1" screw, a 3/8" rubber spacer, two washers, and a white porcelain knob handle, I was able to create two more magnetic attachment points, one in each non-hinge side corner. This configuration creates a door attachment system that doesn't put too much magnetic pull (so you can't open the door), and the knobs ensure I can change filters easily and safely.Finally, these are powerful magnets that are also fragile (although I didn't break mine). To separate them without damaging, follow the instructions to turn them, then slide them off. It is much easier this way. Also, the adhesive seems to stick well to these magnets and metal surfaces, but clean those surfaces well, and do your best to avoid touching the sticky part for the best adhesion. I will update this review if anything changes, but for now I am happy to not have to replace the whole door for lack of a couple of 5 five cent latches.

These work great for mounting medium weight items

These magnets are pretty strong given how thin they are. If you don't put them together softly enough, you can break about 3 of these easily. Just be aware they are brittle

Theses are very strong magnets I had to check the package to make sure that they weren't glued together because that's how powerful they areExceeded my expectations highly recommend them

I needed strong magnets to hold a screen over my garage door when it opens and closes. These hold the screen in place so it doesn't sag and set off the safety on the door. They come with a sticky tape that allows you to place them anywhere and hang items at will.
