Swivel Swing Magnetic Hooks, 30lb Strong Heavy Duty Neodymium Magnet Hooks - Use for Home Kitchen Office Garage Outdoor Hanging(4 Pack)

extremely strong.

Work great- very strong!

The magnets are fine, the hooks are a better shape than most for easily hooking and lifting away, but the swivels are not the sturdiest. If you grab the hook to lift them directly off a surface, be careful to not pull sideways, or one side of the swivel may pop out of its hidey hole. No big deal, easy to put back on, but its surprising when it happens. This is not a practical problem, as youd have to do something odd to have this happen in practice since the hooks swivel to hang staright down.

Large (as described) and VERY strong. I hung photos (in frames) with 3 of these and used the 4th for hanging a kitchen utensil.

The neodymium magnets in these hooks are very strong and they perform as advertised. But READ THE SELLERS CAUTIONS before buying. The 30 lb rating is for a vertical pull, meaning that the hook is hanging vertically from a horizontal surface. If the hook is attached to a vertical surface, it can support much less weight. Why do you think this is? There are several reasons. First, the hook is being pulled downward along the vertical surface, but its maximum adhesion power is perpendicular to the surface. This will tend to rotate the hook away from the surface. Beyond that, there are other reasons that the hooks may not appear to adhere as well as one might think. Magnets are attracted to ferrous materials, such as iron. The reason that the magnets adhere to steel surfaces is because of the iron in the steel. Steel is, after all, a composite of several metals, not just iron. Some steel varieties have far less iron in them than others and the hooks will have weaker adherence to these types of steel. In fact, Id go so far to say that the 30 lb vertical rating on these hooks is likely to be valid only for an iron surface. Got it so far, 1- and 2- star reviewers? There are different grades of steel, some of which contain more or less iron. The less iron in the particular grade of steel in your range hood, file cabinet or cruise cabin wall, the less well that the hooks will adhere. But thats not all. Most modern surfaces are either painted or sheathed with plastic or some other material. Separating the magnet of the hook from the metal with a layer of paint, enamel, plastic or paper in between reduces the adhesion force. Said differently, no matter what is put between the hook and the raw steel, if there is a layer there, the magnet of the hook will not adhere as well. The thicker the layer, the less adhesion. Mr. and Mrs. 1- and 2- star, are you still out there? Yes, there is even still more. If you use one of these hooks on a vertical surface, the coating on the surface can have more or less friction. Some surfaces are very slick. The hook will have a greater tendency to slide down a slick surface than it will on a higher-friction surface. Consider the extreme: take oil or grease and coat the metal surface, then stick the hook to it. Now the hook will easily slide downward and will support hardly any weight. The point is that the nature of the surface that the hook is adhered to is very important. Get it? Its abundantly obvious that the 1- and 2- star reviewers are almost exclusively people who have no notion of these concepts. Im writing this because they have unfairly downgraded this product which works just as advertised. Its a good product. Id buy it again.

Very strong

Would not hold my light weight coat on the side of my locker at work, even using 2 of them.

Update 8/10/18: Im upping my rating as the magnets might perform as advertised under better circumstances, but the metal thickness on the side of my fridge is apparently not such that they can support their full capacity. Additionally, the vendor has excellent customer service and fully refunded my order when I could not use it as intended. If youre going to attempt to hold up anything heavier than a set of potholders on your fridge though, Id recommend purchasing the next strength up but Im giving them an A+ on keeping the customer satisfied. Original review: These have a decent magnet on them but not nearly as strong as advertised. I realize the strength is reduced by shear force, but they wouldn’t hold up a 2 lb broom and I could easily pull them straight off the fridge. I ended up having to use adhesive. Neat, but I wouldn’t buy again.

The strongest magnets I have ever used. I have two that I cannot pull apart from each over. They should be wrapped individually when sending.
