Excellent, required to attach a flower to a handbag for a wedding. Worked perfectly, magnets really strong. Delighted with purchase

The 6 Pack of Neodymium Disc Magnets (30 x 3 mm) is an impressive set for anyone needing strong and reliable magnets. With a pull force of 8 KG, these magnets are exceptionally powerful for their size, making them ideal for a variety of applications, from crafting to office organization. The included double-sided adhesive is a fantastic bonus, allowing for easy installation on various surfaces without the need for additional hardware. I've used them on the fridge to hold up notes and small tools, and they have held securely without slipping. These magnets are also great for DIY projects, as they can be incorporated into crafts or even used in building models. Their compact design and strength make them versatile for both personal and professional use. Overall, this set is a great value for anyone looking to add some serious magnetic power to their toolkit. Highly recommended!

Exactly what I needed. The magnets are very strong, by using three of them next to each other securely holds the foot switch for my electric plinth onto the metal frame, preventing it from being accidentally kicked or moved.

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.

Quite strong magnets but no good for what I wanted them for.

I’ve previously ordered other brands of magnets which turned out to be a little disappointing strength wise, but not these! As advertised, these are very powerful so care is needed. I learned the hard way. When I first unboxed these they suddenly all snapped together producing a loud crack and a spark and one of the magnets instantly shattered, so take care when unboxing and make sure not to place them too close together! Very difficult to separate and need to be treated with care as they are quite brittle. They look solid due to the metal plate coating but don’t be fooled. Anyhow, I stuck a few of these to the wall of my shed and can confirm that a ‘single’ magnet is strong enough to secure a tool (see my photos). Size wise these magnets are about the same size as a 10p coin. Would I order them again? I would say yes, but I would be more cautious and treat them more carefully in future.

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.

These things are mighty! Big enough but fairly thin, they work really well
