Well worth the money
Excellent magnets, they are about the size of the batteries you put in various car alarm remote controllers, and are quite strong. I used one to hold a security camera to the ceiling and it does the job very well. I don’t think one could hold 8 KGs, but two together may be able to.

Very strong shallow magnets
Very strong magnets for the size. The 4 were packed well to a point. Unfortunately I struggled to get them out of their bag. And as I did so, the magnets flew out of their individual foams, stuck themselves together so violently that 1 magnets chipped severely ans the chip flew and hit my face. Then they proved to be so strong my arthritic hands could not separate them and I needed help. (Even the friend who helped me was impressed with their strength). I wish they were packaged in a slightly larger bag to help make it easier to get at them. Defo value for money. Will defo hold up fairly heavy jars by their lids to bottom of a high shelf. I recommend but please take care when opening them. Don't get injured like me.

Insanely strong magnets!
Shocked at how strong these are! I thought I would need at least 4 of these to hold up a magentic whiteboard to my fridge, but nope, just one is enough! These are a good size and an ideal thickness for the task too. They come with spacers and look weird at first glance until I realised why they are needed, it will be a hard time removing these from anything that they stick to and a child is going to have a tough time removing them, which makes sure the board stays pretty safe

They work, their strength!
Excellent magnets! If you aren't impressed with the strength of these nothing will please you. "Does exactly what it says on the tin" As they used to say in that ad! 10 out of 10 for product and seller delivery time. Try not to let them attatch to each other though!😆

OK for smaller Jobs.
Quite strong magnets, but too small for what I needed them for. I should have read the measurements, so my fault. Otherwise their OK to use on other projects, good value for the money, I can't see them breaking apart. They do include sticking strips, so any installation should be easy enough, being smallish, they don't weigh much. Recommended for smaller Jobs.

Good strength for the price.
A decent strength. I bought it as bought a blu ray on ebay but it had a blue protector lock on it. The seller said that he received it like that. Removed it with these magnets but it did take a few tries.

Brilliant, absolutely brilliant
These were absolutely brilliant. I’ve got sliding wardrobe and for some reason I don’t have my floors are slightly out or whatever the doors never used to shut tight against the wardrobe itself. I got this magnet put them on the top of the door inside the door frame runner and it works brilliantly. The door is now shut. Close. The only thing I would say is you probably gonna have to use maybe gorilla glue on the magnets to keep them in place cause the 3M double sided sticky Pads don’t really stand up to the test of time but other than that these are brilliant they’ve solved a problem. I thought I’d never get solved.

Utilisés pour plaquer des planches de CP 3mm sur un nid d'abeille, en vue de découpe au laser. Pas trop épais et super efficace pour le maintien des planches. A recommander

TL;DR: Sehr starke Neodym-Magnete mit hoher Haltekraft. Alle Magnete kamen unbeschädigt an, der vormontierte Klebestreifen hält gut. Für den Preis ein wirklich gutes Set – für meine Anwendung fast schon stärker als nötig. Ich habe die Magnete für ein 3D-Druck-Projekt gekauft. In meine gedruckten Bauteile habe ich passende Aussparungen konstruiert, in die die Magnete eingesetzt bzw. eingeklebt werden. Die angegebenen Maße von 60 × 10 × 3 mm stimmen und passen sehr gut für solche Anwendungen. Positiv aufgefallen ist mir direkt beim Auspacken, dass alle 16 Magnete unbeschädigt angekommen sind. Bei Neodym-Magneten habe ich schon häufiger erlebt, dass einzelne beim Transport brechen oder kleine Absplitterungen haben, da das Material relativ spröde ist. In diesem Set war jedoch alles sauber verarbeitet und vollständig. Die Magnetkraft ist wirklich beeindruckend. Die Magnete ziehen sich sehr stark an und lassen sich nur mit etwas Kraft wieder voneinander lösen. Für meine Anwendung sind sie fast schon stärker als notwendig, aber das ist natürlich eher ein Vorteil – lieber zu stark als zu schwach. Praktisch ist auch der bereits aufgebrachte doppelseitige Klebestreifen. Dadurch lassen sich die Magnete schnell und unkompliziert fixieren, ohne sofort zusätzlichen Kleber verwenden zu müssen. In Kombination mit passgenauen Aussparungen im 3D-Druckteil funktioniert das sehr gut. Insgesamt bin ich von dem Set positiv überrascht. Für den Preis bekommt man sehr starke Neodym-Magnete, sauber verarbeitet und mit einem praktischen Klebestreifen. Für Bastelprojekte, 3D-Druck-Anwendungen oder allgemeine Befestigungen meiner Meinung nach eine klare Empfehlung.
