Worked well

I used the block as one half of a magnetic latch for a tool box. The other half comprised three short lengths of fencing wire inserted end-on into the mating surface.

works well , but they are brittle .

Used these magnets to hold extra bits in my drill driver box .

They work great , but I broke the first one by tightening the screw with the impact driver , don't do this , tightened with a screwdriver no problem .

Good but .....

Magnets arrived very quickly but arrived with 2 cracked magnets in the centre of the pack. Attached the surviving magnets to the underside of a small key safe that can now solidly attach to the underneath of the car while parked.

Hi Stephanie, thank you for your feedback! Sorry to hear two magnets arrived cracked, we package all our magnets with a generous amount of bubblewrap to prevent any breakages during transit but if you'd like to send us email with a photo of the cracked magnets along with your invoice number we can arrange a replacement. Kind Regards, AMF Magnetics.
