LOVIMAG Strong Neodymium Bar Magnets with Double-Sided Adhesive, Rare Earth Metal Neodymium Magnet for Fridge, Scientific, Shower Door, Office Etc, 60 x 10 x 3 mm, Pack of 4

I have a 15 yr old range hood that has 2 SS baffle filters. The plastic latch on each deteriorated so the front end wouldn’t stay up. New baffle filters were $140 each. So I thought it was worth a try to see if magnets would hold them up. First, I confirmed magnet would stick to my stainless. Then I got the largest size that would fit, and put them inside the hood, along the hood/baffle frame. They were strong enough to keep the filter up pulling thru one layer of stainless (see screwdriver pic). I put two in the front edge, would have been plenty , but since I had 12, I then put another on the inside edge, so used 3 per filter. Definately 3 was overkill, but don’t need the filters crashing down on my induction cooktop. Warning: these are STRONG magnets so when you seperate them- keep them 12” away from each other or they will slam back together. I chipped one corner learning this, but still used it as the magnet was hidden. ALSO, if you separate from each other- and don’t use them all, KEEP THE SPACERS BETWEEN THEM. If you don’t, they will be very difficult to seperate. Yeah, they are that strong. Given the size and weight, they are far stronger than imagined. And saved me $200 by not having to buy new baffle filters.

I'm working on a project for my airbrush booth, and am making magnetic exhaust hose couplers and these magnets are the perfect size and strength. I wanted black magnets instead of the typical silver These magnets are strong, very strong actually, when attached to each other, it takes a lot of pull to separate them. They have a nice epoxy coating that's not chipping off, seems very durable. The magnets dimensions are pretty spot on, they're also nice and thick. They come with adhesive pads that work very well. I do clean the surface of the magnet and the part I'm attaching it to with some alcohol first to ensure a clean surface. For the price, quality and strength, these magnets are great for my different projects and will continue to buy more as I use these up.

The other reviews have me questioning how often others work with magnets or I was lucky. Firstly there is plastic that separates each magnet, but to be honest they are quite a pain with the plastic in-between since it is slick as you slide one off it can cause two magnets to connect bypassing the plastic. Personally I had no issues separating two magnets stuck together. You just slide them and they come apart easily. Breakage? Either others packages were handled rough during shipping or I lucked out on a strong batch. While trial-erroring my project I had them connect to each other, drop on the floor (carpet so that's probably the savior) but still many double connects as I was using them to hold a heavy curtain up. None broke. Strength: You have to figure out the utility. If you're trying to hold something up, but placing the magnet perpendicular to it, you will need a lot more magnets if the object is over 5lbs I would say. However, when the the magnet is parallel to the object position the strength is more. I stacked 3 magnets across a 7ft metal beam to seamlessly hold a blackout curtain up. The magnets had to be on TOP and not on the side; on the side the curtain would immediately fall as stopped holding it. With the magnets on top, well...its been up for 3 weeks with zero issues. Fridge use: yes, or whiteboards for calendars etc... Garage use: yes, from tools to storage jars, when done properly these should last for awhile(easy 10 years) Car: yes, under the hood, extra holder for flashlight, just be mindful of winter weather and how the cold/heat affect magnets long-term.

Strong magnets when paired together. Pretty average otherwise. Super fragile too.

These magnets are very strong. But when I held one of these magnets over my “snake egg” magnet and allowed it to jump up to this magnet, it broke the magnet. I’m not removing stars for that, because they are thin, and I don’t know if this is standard fragility for any magnet this size. I have seen reviews for large magnets that have broken when dropped. Maybe they need to be handled with extreme caution. I will say that I found it interesting when I attempted to piece together the broken halves, they would no longer fit back together. They became immediate polar opposites as soon as they broke up…like a bitter divorce. They still cling to other magnets, but not the ends where they snapped. Knowing this bit of information, it makes sense that if the magnet has a flaw and begins to break, it will snap. I bought these to add to a magnet game my sister had. Instead of using a provided rope, we used a spare top to a plastic container and placed these pieces under the top to make the game more interesting. They were smaller than I expected, but I will say I had a chance to drag out my ruler and compare it with the dimensions on the description. It’s not like they gave erroneous dimensions in the description. So for what I paid, and the fragility of magnets in general, I have no reason to reduce stars based on my ignorance. Just be careful when you use them. If you drop them or let them snap to another magnet, there’s a great chance they will break. So be careful. One thing I did notice on these magnets is that one or two have pits or indentations in the edges. But again, the magnet did the job I intended, and I wasn’t entering them in a fashion show, so I won’t be removing stars. I mention these things so perhaps you’ll buy these with a bit more awareness than I had; and you will handle them with more care. Enjoy!

As a magnet, they are very strong but VERY brittle- do not drop them. As far as sticking to true stainless steel, they do NOT work. I threw them in my toolbox to attract small drill bits.

Magnets are great, the DS tape is not as strong as I needed, so I ended resorting to superglue. I broke one in half on purpose, because it was too long, but while it's still magnetic, using the two pieces side by side are not as strong as one solid piece. Just food for thought.

Pros: These are slightly thicker than the .3 versions and I find them sturdier and yet still easy to slide one over to separate from the pack provided you do it with the plastic divider at the same time. I use them to attach a screen to my apartment black metal storm door that has a deadbolt lock meant to keep intruders out and it does a good job of that. However, its' scroll design does nothing to keep flies, gnats, or spiders from entering so I purchased a screen netting and attached it with these magnets every few inches. It works well enough but because the storm door itself doesn't fit snugly on the top or bottom threshold it's not foolproof. Sure does help a lot though, especially whenever I'm cooking in the summer and must leave the front door open for fresh air! I'm willing to pay more for the black ones because it looks a lot better when everything matches or blends in with the decor. Con: These last better than the plain steel versions, but rust will still eat any finish that's painted on magnets in about a year where I live. It's the salt air and constant moisture that comes in off the ocean that is hard on both cars, metal outdoor furniture and that's just the way coastal weather is, not the fault of the products. Aluminum and stainless steel do better, but are also more expensive so you have to decide what you think is best for your situation. They are exactly as described, adhere well to most things, and although they come with an adhesive strip for when you don't have metal to attach them, I've never used them for that purpose. Can't comment on it because I rent and we're not allowed to damage the wall with adhesives or nails. Caution: Not for people that have pacemakers because it may interfere with the safe operation of them. I have no idea how strong magnets are that affect pacemakers, but it would be helpful if the seller and/or manufacturers could comment on that.
