Ultra-Strong Ceramic Round Magnets (0.7x0.2"/18x5mm, 30 pcs) - Heavy Duty Magnets, Non-Corrosive, High Thermal Resistance, Versatile For Home, Office, Workshop, Whiteboard, Fridge And Hobby Use

These little magnets are great! They are strong and work great. I am a teacher and I use a white board to write on but I also use it to mount pictures. Our white board is old and wavy in spots so magnets do not hold well but these little magnets holds everything great. We also use them to play a new game where the magnets are in a circle and you try not to let them attach to another magnet. They worked great for the game also. We had fun playing with them Christmas.

It works exactly as expected. I decided to buy one of these small magnets and use it to my indoor Hue smart Home sensor that way I don't drill into the wall or position it tacky on top of an object where it becomes clearly visible instead it actually looks like it's a part of the natural decor/house. Pretty easy to install just peel the thing off stick it onto the wall hold it there for about 30 seconds and it should stick if I'm not mistaken. This is 3M VHB which is shorthand for very high bond M3. Basically hold well and the longer that it sticks onto the object the better bonds. They're pretty easy to use and ever since I used it in this product now I'm brainstorming for ideas on either to hang my fancier kitchen knives using a magnet that sold by the same vendor of this circle magnet would get creative. I think it's worth it for the money you get a decent amount of them. It's pretty straightforward simple to operate. Nothing confusing, peels off like a standard sticky tape. It may feel like it's not super sticky, but that's the way the M3 is designed once is stuck on the wall it will hold/grab. It starts to bond once it touches a hard surface. The magnet themselves are thicker than a quarter but about 3/4th of the size. It doesn't slide back-and-forth once it's on just put it into the wall and give it like a 30 second push and hold. It's ready to go generally with m3 type of bonding stuff. You have to wait a little bit, but this is not the same as command tape they're pretty much quicker and longer it stays the more grips, but I would probably just wait a bit before putting something heavy in there. It works for perfect for my application makes everything flush and it looks like it's part of the wall

Strong magnets that worked well for hanging a curtain. I'm sure I will use for other projects.

Strong magnets with good holding power for their size. The adhesive backing works, but it’s not the strongest and may need extra glue for heavier items. Overall, decent quality for light use not for heavy weight.

These magnets were used for crafting. Very strong. Perfect size and adhesive holds very well.

I buy these every year for school pictures instead of the magnets the school sells that cost double the price. They work perfectly and hold photos really well. I give them to family and friends so they can display the kids’ pictures on their fridge, and everyone loves them. Strong, affordable, and such a smart money-saving option. Highly recommend!

Magnets work well, but I’m not ultra strong. We use them on a board outside and they are still constantly falling off.

Really good magnets. I've not dropped one yet so I can't comment on durability but they're pretty thick and heavy. I used them to put up under cabinet lights in the kitchen and they held up well. The adhesive is strong but the lights I put up are very light.

Super ! L'aimant est assez puissant tout en ayant une dimension raisonnable, idéal pour des magnets un peu lourds ou si l'on souhaite faire tenir pas mal de papier surtout si le papier est un peu épais ! Les 4mm d'épaisseur y sont pour beaucoup je pense. Le prix est aussi très correct ! C'est un 5/5 mérité

Les aimants sont puissant pour ce que j’en fais ! Parfait

Tienen muy buena potencia, pero los quebraron/estropearon durante el manejo del paquete. Afortunadamente no necesito estética por eso me los quedaré.

So useful, no issue with falling fridge magnets. Have to buy more.

Zijn niet zo sterk moet er al 3 gebruiken voor waar ik ze voor wou gebruiken om binnenkant van reborn pop te plakken zodat het magneetspeentje blijft zitten
