Realth Disc Magnets Diameter 12mm x 3mm Neodymium Small Magnetic Round Magnet for Fridge Office Science Project and Craft 10 Pack(MC1210)

Good adhesion generally. Difficult to score ease of separation as that contradicts adhesion. However these are strong magnets.The only drawback is where theres material between the magnet and metal.surface that has a sliding force, the magnets slip off quite easily.Overall good product.

I required a drill caddy for my Drill Press and I needed something to stop the drll bits rolling off onto the floor. These magnets did the job

Very weak magnetism, almost as if they were not real Neodymium magents....I had some 20mm ones (from Amazon) a while ago which were significantly more powerful than these, these are pretty poor.

Super magnetic but they are fragile which rendered them unusable. They wouldn't withstand the way I wanted to use them on a mozzy net that would have been put up and taken down every day.

Waste of money.

Extremely strong magnets, excellentHighly recommended

So on opening the package I tested the strength of one if the magnets, unfortunately it snapped in two pieces, but all the other nine were fine. Great customer service as I had a full refund.

Used these to hold metal distribution boxes on light rig did the job well
