30 Pack Strong Neodymium Magnets Fridge Magnet Bar 30x10x3mm Heavy Duty Magnets Bar Rectangular Rare Earth Magnet for Fridge, Home Organization, Photos, Postcard, Iron Tools

I read the reviews & read that they were strong & break easily.What I didn't know was that if you get any metal, anywhere near, the SEALED package, it will just "fly" over there & stick. It was difficult to cut through the plastic seal all around it. Scissors, single edge blade & paring knife all stuck.When I finally cut through the plastic (struggling with the paring knife) - I knew to SLIDE the magnet off the top. That being said, I didn't know to move the pkg of magnets far away from the one I removed. Immediately, it flew back & broke the 2nd magnet on the pile. It took me 3 broken magnets to get the hang of it. I did use the broken ones, they only broke in half, so I matched them up.My suggestion, put the bottom magnet on the item first, then the top magnet (if u are using one), with the tape still on the top of the 2nd magnet. I used 2-3 sets on my under cabinet lights and lined them up on the light. Then, when I got over to the cabinet, took the paper off both magnets before sticking onto the (under) cabinet. I put up 3 lights this way and it all went perfectly!After all is said and done, I am VERY happy with these magnets.They are tiny but mighty & I no longer worry about the lights falling down (this happened with all original magnets that the lights came with)I definitely recommend buying these!!

Amazing strong magnets...solved tricky problem of hanging calendar magnetic board on freezer door. If I hadn't put extra magnets on top of and underneath undersized right angle hanger the board would slide down to floor... I'll try to get a decent photo...

Great, strong magnets. Used them to replace fastening clips on HVAC return in ceiling. Worked well.

not as strong as I thought they would be, but they are working for what I needed

The magnets are very powerful, be careful not to smash your fingers between them.Although difficult to remove, I used these magnets to make connectable crochet amigurumi -- they were powerful enough to make the piece stay together!

Not very durable. I bought them to hang a set of magnetic chip clips. They would fall off the cabinet and break on the floor. The magnet strength wasn’t the best. Easy to remove, since the sticky strip didn’t really stick. Disappointed that they didn’t do what they needed to do.

Perfect for the Ring Alarm contact sensor. I have very narrow trim on the fire-door to my garage - too wide for the Ring Alarm contact sensor. Used one of these magnets with the included dual sided tape instead of the Ring magnet and it worked perfectly. Took less than 15 seconds to install. Remember to offset the magnet away from the contact sensor push button as shown in the photo! (Test the position of magnet when you install)

Couldn’t believe how strong these lil things are!!
