Realth Neodymium Disc Magnets with Holes, 0.98" x 0.19" Hole 0.62" Round Magnets for Research, Industrial & Educational Purposes (MC822)

Very strong magnets. I used them stacked on top of each other and put them on the on/off button on my Xantrex 2000 inverter that is in the storage bay compartment in my motorhome so that camping/fishing gear won’t accidentally Push the button and turn it off. Picture attached.

These worked perfectly for what I needed it for!! Extremely strong for size!!!

These magnets are very strong and do a great job at holding however be careful letting them attach to one another too quickly as this often breaks magnets, I have already lost 5 of 20 ordered. There are other versions of this magnet with backing or protection that may better suit your need.

Perfect for the project I needed them for

Magnet Strength is 5/5 but to its own detriment. The 1st time I let the magnet click together, one of the magnets broke in half. When I picked up the broken half that fell, it clicked/attached and broke again. So now I will be sending back one full round magnet, one half and 2 quarters.

Strong magnets but one slip and they shatter easily.

Watch out, these slam together HARD and could give you a serious pinch.They easily break if you allow them to slam together, don't do that!!

These magnets were intended for middle school science lessons but were way too strong. Adults could barely pull them apart from one another so these would not work for 7th and 8th graders.
