The adhesive force of these (I got the130lb version) seems as advertised...it is VERY difficult to pull these directly away from an ideal metal surface...I've only able to remove them by angling them from one side. So they're strong enough to hold a lot of weight, but still easy enough to remove when needed. The shear force (sliding along a surface) obviously can vary due to the level of friction on the surface but they seem more than strong enough to hold fairly heavy items on a vertical plane. For reference I was able to hang a standard sized hammer on the side of my garage fridge, which is a fairly slippery surface, on one of these, and it stayed put well enough. These were strong enough that I could locate floor joists under my hardwood, because these magnets were easily attracted to the nails in the subfloor. Ditto for finding wall studs through sheetrock. This will come in extremely handy for home improvement tasks. I'm glad I bought these. They will be very useful to have around. If you're going on a cruise and need to hang items on a vertical surface these are probably the ones you want (130 lb). Anything less may slide down the wall with anything but the lightest weight items.

So glad we took these on our cruise. Used all 4 of them in the bathroom - to hang up wet swimsuits, bath scrunchies, etc. Really convenient, took virtually no space in our luggage, and gave us extra way to hang items. They are sturdy and hold firmly to metal.

The thing is, not only do the magnets have to be strong, but the hooks have to be well fabricated to support the weight. Both are excellent. Bought these to hang things off the side of a metal table (a welding table). These hooks can hold tools, a welding helmet, or a brush and dustpan. They are fantastic. They are small and unobtrusive. I looked at a lot of different options and this one came out at the top. I affirmed the five star rating with our experience. Update after months of use: They are everything they purport to be. Top Marks.

These are great magnets. Super strong and heavy duty without being too big.

Works great! Very strong magnet and good hook

Good quality, really strong and they can cope with a lot of weight. I hang kitchen tools and pot holders off of them. I can NOT pull these magnets straight off. I have to slide them over to the edge of the refrigerator, and remove them from the side.

We bought these for numerous applications around the house and they don't dissapoint. Very strong magnets with good appeal.

I needed a super strong magnet and I needed it quickly! This product exceeded my expectations! Packaging was easy to open yet prevented the magnets from adhering to one another, magnets and their hooks were easy to put together, they are small in size, but able to hang a substantial amount of items. (Honestly, more than I thought they would due to their size.) They're not big or bulky and are relatively thin, especially with regards to their strength. Definitely would recommend and will be ordering more!

Très solide

Ces crochets ont été acquis pour une prochaine croisière. Leur construction est de qualité. Nous avons sélectionné cette capacité d'accrochage. L'objectif étant d'obtenir une meilleure résistance lors de leur usage verticalement.

doors or on cruise ship walls. Holds my Christmas wreath in place

I ordered the 4 pack of 100 lb strong magnets and paid a premium over other magnets for sale on Amazon based on the indicated strength. The magnets look and feel great, were easy to assemble (just screw hook into base) and were delivered sealed in 2 bags, one holding the hooks, the other holding the magnets, and the bags were in a small box. I tried the magnets on several different metal surfaces and am using them on my fridge to hold silicone kitchen gloves and a wreath on my door (for Xmas time). The reason for the 3 stars is they can NOT hold more than 1.5 pounds of weight (no where near the indicated 100 lbs suspended or 27lbs vertical). It can hold one of those kitchen gloves alright but with 2, it slides down.

These are strong magnets I am sure a lot of cruisers have purchased and reviewed already. They worked like a charm to stick to the cabin wall hang bathing suits or towels. But since then we have found other uses for these we have hung lights and other things but in a pinch my husband used one to find a stud lol
