DIYMAG 8 Pack Strong Neodymium Bar Magnets Powerful Rare Earth Magnetic Heavy Duty Metal Magnet with Double-Sided Adhesive for Fridge Kitchen DIY Craft and Office Science, 40 x 10 x 5mm

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.

These magnets are great quality and unbelievably strong. I used one set to hold a sunscreen panel against my front screen door, and it stays put even in windy conditions. Just be careful when handling them because they snap together hard enough to pinch your fingers. Solid product if you need real holding power.

Handle with care. Very brittle. They'll snap on each other quickly! Works good with my project.

They are holding very well. I used those to hold a plywood plank against a metal surface.

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 bought these to help adhere a fireplace cover to the front of my fireplace. The magnets that came with the cover are really weak and I had hoped these would be able to hold it in place. There is a thin layer of fabric between the magnet on the cover and these. They hardly hold to the inside magnet (yes, I have the poles correct). If I apply them directly to metal, they stick really well, but if there is anything between, they barely hold. They are also very fragile. I was trying to get the plastic package open and it flew out of my hand. One of the magnets shattered when they landed on the table and another one got a chip in it. While trying to get them stuck to the fireplace blanket, I dropped one from about 18 inches and it broke into 3 pieces. I'd return them, but 3 of them are broken.

My garage fridge is older than your mom, and will likely outlive you. Will certainly outlast the junk being sold today. It sucks energy harder than an emo teenager, which makes it even worse when the kids don't make sure the door closed. A new door seal is more than a new fridge, so ordered these magnets for a cheap fix. They work great, even though they don't touch. I used one on the door and one on the fridge body for extra door closing strength and hold. Thin enough to fit in the gap, strong enough to pull the door closed, or force it open if you get the polarities wrong. Best of all, I don't have to rely on the kids to be responsible anymore. Had none broken, and didn't break any during installation. Use the sliding method to separate. They have nifty plastic spacers for shipping that make getting them apart a bit easier. Would buy again for my next garage fridge, but, will I ever need a new garage fridge?

They changed the magnetism strength of these magnets. I have been ordering the same product for 5 years and now they changed them. I have weighed the magnets and the old ones were 24 grams and the new ones are 21 grams. 3 grams difference is a lot. Very disappointing that this has happened. I will not be making further purchases of this product.
