These are strong! They can and will bite (pinch) you if you're not paying attention.
These magnets are a blast to play with but please be careful as they will pinch you. These are simple with no moving parts and hold on tenaciously. They will seem to jump from your hand to a ferrous metal item before you realize it's pulling. I've had pliers, screwdrivers, drill and driver bits leap to the magnet with surprising speed and energy. They will remind you to, above all else) safety first then think out your steps before you start. I really like these immensely and have purchased more but from a different provider. These are rated at 110 lbs pull and that's plenty. The second set are rated at 150 lbs pull like 'Tim the Tool man Taylor says' more power is what's needed. Lol. What could be a great item as an accessory for these is a kit to make handles for easier handling of these magnets. I made some from scrap pieces I had laying around. All in all I am extremely happy with these. For me they are well worth the money.

I bought these magnets for a special project to mount to welding clamps. They worked fine, and the clamping force was adequate. The one caution I would make is don’t over tighten them. I broke two by putting too much torque on the retaining screws. I don’t believe the magnets themselves were defective. I just put too much pressure on them. The remaining set that I did not over-tighten are working perfectly.

These are kinda like The Wizard of Oz...great and powerful. I bought these to hang the artwork of my granddaughter on the refrigerator. Today, she brought us our Valentines and I made the mistake of putting two magnets into one hand. I had no control over their movement...they immediately stuck themselves together ... with the skin of my finger between the two!! I was truly unable to separate them with my available hand. I yelled for my husband and he struggled, but got them apart...then came the blood and almost immediate bruising. No, I am not kidding. This is 6 hours later and I need to keep a band-aid on it because it keeps bleeding. I admit that my skin is old, 68 years old, so it doesn't take a lot to injure, but this was a bizarre incident. These are excellent magnets and I, in no way, blame the manufacturer - this is a great product....if you want to maybe move a CAR!?!?!?! LOL Ok, so that's not true, but they are very strong. Now, onto the search for a magnet of a much lesser power. Hope this helps in your decision making.

I bought these top secure some cabinet doors more strongly than the ones which initially came with the cabinets. I have large dogs who know how to take the cabinet's handle in their mouths and pull until the cabinet opens. (They're far too smart for MY own good.)
Using 4 of these each door has solved the problem completely.

I have used the rest of them for something I had not planned. I do woodworking as a hobby, and I have a substantial dust-filtration system. The hear of the system is a https://www.amazon.com/gp/product/B00064NPXO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
and it can be difficult to replace the lower bag after I dump it, as I think I need at least 3 or 4 hands to hold it in place so that I can secure it with a clamp. I had been using tape to hold it in place, but the magnets work FAR better (and are completely reusable, unlike tape). Tape is cheaper, but I prefer the magnets here.

These are EXTREMELY strong (the dogs trying to open the cabinet door both weigh in the 115-135 lb range, and they can pull VERY hard), and I would recommend them to anyone who needs mountable magnets for any purpose.
