Great for hobby work
Used for miniature hobby work and they work very well. Strong attraction and easy size to work with.

Good and strong though
Bought these for a jewellery box project but (unusually for me) read the warning label and realised I shouldn't put them close to mechanical watches so that idea was out! Good and strong though, no doubt will have a lot of uses. One thing to note, there's a section on the warning label about if they're swallowed (because they're so small) surgery WILL be required. The warning makes a lot of sense and gave me second thoughts about using them in case they come loose and the children get a hold of them. If you have small children in your house, think twice about using these unless you can be absolutely sure they won't come away from whatever you use them on. They're now stacked on a high shelf in my garage, however as described they're great little things so 5 stars.

Great magnets
I bought this magnets to fit in modeling pieces that can be changed in my Warhammer army. They work great and tho small they do fix the pieces together and allow to pose them at will The only problem i found is that they are so strong that even epoxy do not hold them in place unless you make a cocoon arround the magnet.

neodymium disc magnets for craft.
The magnets are well sized, came quickly and hold well for their size. I have yet to apply them to my project but they look as if they would do the part perfectly. the little container was pretty nifty too.

Great magnetic power
Great magnetic power!! But a little too hard to deal as this is too small. I didnt think it was this small but the dimensions are right. Haha my bad!

Insufficient packaging
While the magnets themselves are fine, they did not come in the storage box pictured, they simply came taped to the front of the invoice/shipping receipt. This means the product description is misleading as it clearly states the following: "Supplied In A Tough Magnet Expert Reusable Storage Container With Applicable Warning Label. Magnet Expert Health & Safety Data Sheet Included With Order" Neodymium magnets of this size are incredibly easy to lose due to how small they are, and they're also potentially dangerous, as they can easily be ingested by pets or children, and could cause internal injuries. Anycraft-UK who shipped these should seriously reconsider how they ship magnets as their current method is simply negligent and potentially dangerous!

Para manualidades u otros usos similares van genial
Tienen mucha fuerza para lo pequeñitos que son. Me sirvieron para solucionar un problema de un destornillador que necesitaba que sujetase las puntas mejor. Puse un par en el fondo del hueco para las puntas de destornillador y ahora las puntas ya no se caen. Y los imanes tampoco se salen porque tienen mucha fuerza y se pegan al metal del propio destornillador. Muy contento con el resultado y se me ocurren un montón de otros usos para ellos.

La perfection avec un anémomètre fabriqué à la maison
Maintenant que je suis à la retraite, je peux me permettre de faire des machins électroniques/informatiques pour mon simple plaisir. Récemment, je me suis mis à fabriquer un anémomètre et je suis assez proche de quelque chose utilisable. Pour l'affichage, j'affiche la vitesse du vent (j'attends un bon coup de vent d'Autan pour ajuster mon comptage) et comme j'avais de la place, j'affiche aussi la témpérature et l'humidité. J'ai trouvé un modèle 3D sur Thingiverse et j'ai imprimé les pièces, sans problème particulier. J'ai opté pour un boîtier IP66 (étanchéité correcte) destiné à contenir l'électronique et un petit Arduino Uno. Le code est fait maison. Ces petits aimants (j'en ai mis quatre) sont associés à un capteur à effet Hall et à chaque rotation du moulin, je récupère quatre passages que je traite et convertit en km/h. Ca fonctionne vraiment bien et je suis très content du résultat. Le vraiment seul problème avec ces aimants, c'est qu'ils sont vraiment très petits et j'ai oublié où j'avais stocké la première livraison LOL la deuxième livraison a trouvé sa place mais j'ai demandé à mes enfants de tenter de me rappeler où les retrouver

Calamite potenti per la loro dimensione.
Calamite molto piccole, ma con una buona potenza di adesione (fin troppa per le mie necessità). L'unica pecca è il prezzo "alto" per la quantità di magneti, ma la qualità si sente.

Buyer Beware
Neodymium? really? I think not.. just small magnets. No pull. Claim is 19gr it’s 9g at best.. Don’t bother.
