What we liked
- + N52 grade with a listed 0.3 lbs pull force, firmer than standard N35 at the same size.
- + Exactly 3mm x 1mm, with the listing noting they fit a 3mm pin-vise hole and sit flush.
- + NiCuNi triple-layer coating on all 100 discs, and the listing mentions polarity marking during assembly.
Trade-offs
- - A pack of 100 costs more per magnet than the bulk packs of 250 or 1000.
- - Pull force is small at 3x1mm, so heavy models need larger or more magnets, and polarity must be checked.
