DIYMAG 12 Pack Waterproof Neodymium Bar Magnets with Epoxy Coating, Powerful Permanent Rare Earth Magnets, with Double-Sided Adhesive - 60 x 10 x 3mm, Pack of 12

Plan project wisely first. First off, quick delivery, great seller. I may be a little harsh on the review but mainly due for my issues durring use and the seller has a better but more expensive option. Con1- 3m tape will not adhear on felt or fabric for very long mounted on the side of an object. Even with pressure for 1min and left to dry for around 24hrs. The magnet will slide/pull off if shear weight/weight is applied. Using glue with the 3m to try to re-mount did not work since the glue would not cure or hold well on the 3m tape. Like I said, did not work well for my use but the tape method could work on a clean, flat surface and possibly on the side of a flat, clean, non fabric surface. Wear clean gloves when applying the tape to magnet or to surface. Dirt and oils will degrade the glue and will not set or stay in place, so make sure your tape is prefectly lined up with the magnet when applying and applying to surface. Con2- even though it should be well known, these are very hard/brittle magnets. If another magnet hits another or a metal object is pulled into the magnet, it will break and or shatter. use caustion. Better option to these are the magnets with brackets that have pre drilled holes that come with screw. Helps protect the magnet on 3 sides and mounts much better. They are more costly and do require them to be screwed onto location. These are also available through this seller. I would even say, using the backet ones with glue or double sided tape is a better option since the magnet would be more protected from damage. Do not store or place magnets near electronics (tv, cell phone, computer, gaming console) or any type of digital storage device. They will be damaged, erased or destroyed. This is basic practice with just about any magnet, so use caution. Ferrous materials (steel/iron) can and most likely will become magnatized if left on a strong magnet for awhile or if the object is slid off the magnet to many times. Rock/pull off object, dont slide it. (Thus why mounting is important). I tried mounting a few about 1-2in side by side( verticle and horrizonal) to give additional mounting strength but the magnets would attract eachother and the one with the weaker glue would come off and stick to the other. Thankfully they did not break. In summary, they are pretty strong and have many applications, they just did not suit my use perfectly and there are better options for similar uses. Instead of returning mine, I'm sure I will figure out another use for them. Only difficult part will be A- storage and B-removing the tape or de-glueing the tape for storage then re-glueing them. A nice option from the seller would be to provide non drilled brackets to place these in for added protection.

I needed a good method to seal the shower curtains to the wall to keep water where it belongs. These magnets are coated (won't rust) and are plenty strong enough to hold several thicknesses of vinyl shower curtain with no issue. They are fragile, so I stuck a magnet to the shower wall and sealed the edges with silicone. Then, using some vinyl trim I had (which matches the shower wall) if stuck a magnet to the trim and encased with silicone. This protected the magnet from breakage and made it easy to separate from the magnet on the shower wall.Now I can pull the curtain tight and secure it with no worry of water getting on the floor. I also made on to secure the bottom of the curtain to the (cast iron) tub. You would not notice them when not in use and look and work so much better than products that were made for this purpose.It has been 2 months, and I have no rusting and no issues at all.

Magnets are strong, I give em that. But the magnets crack/break often when magnetized to a surface or another magnet. Idk if that’s a common thing for magnets or a reflection of its quality. Good thing is when one magnet breaks, it becomes 2 magnets.

These magnets come securely packaged with plastic strips separating each magnet, and for very good reason. They say 18 pounds of pull. I'd guess that's underestimated! On my desk, I removed a single magnet and laid it at least 2 feet from the package. As I removed my hand, the single slid across my desk, swiftly joining with the others in the still opened package. The impact broke 2 other magnets, shattering them like glass. My mistake, which I will not repeat! My bad! Handle with care as instructed! They are SUPER magnets!! I'd buy them again in a heartbeat!

I purchased the DIYMAG Strong Neodymium Bar Magnets. The magnets arrived with plastic separators between them indicating their strength and difficulty to separate. I have attached the magnets to task lights, solar lights, and an egg timer. The magnets stay connected to metal surfaces very well. I also use the magnets to keep a sunroof screen on the car when parked during the summer. To not scratch the paint, I wrap the magnets in duct tape. The magnets can be used for a variety of things. I have purchased them several times and will purchase more when needed. On occasion I have broken the magnets in two when separating them. It does not affect their strength, durability or function. They are great, strong magnets.

The magnets themselves are quite brittle and very easy to break, but they are pretty strong and I haven't had problems with them sticking to things. However, the adhesive strips that come with each magnet are absolutely awful. Every single thing I have tried to attach to the wall with these things has fallen off do to the adhesive just failing after a few days/weeks. These things put me off from ever using any sort of adhesive for hanging things on the wall again, I'll just deal with the small holes in the wall.

Great magnets and double stick tape supplied is good quality; one of the magnets in the stack was broken into several pieces, else would be 5 stars.

I got these to use in my motorhome. I had a furnace cover that was screwed in I wanted easier access to. I put some magnets on the cabinet frame and cover. Screws held things in place well. I have about 500 miles or so on it, and they have stayed in place great. The door never moved when I wanted to to stay closed, but was easy to open when needed.
