Be aware that this thing is super strong and will attach itself to any metal nearby ...

As claimed in the product description the magnet is very strong. I purchased it to help locate studs on the outside of my house (built in early 70s) that has aluminum siding on it. To my surprise I found the nails in the studs very quickly so the magnet did as I had hoped it would.
Be aware that this thing is super strong and will attach itself to any metal nearby or draw metallic objects to it from a distance and at a very high speed.
I've only used it once for the intended purpose that I stated before so i cant comment on the performance of any other intended uses.
Definitely worth the money for the use I needed it for.

Not a "toy" for young children. Will use this for picking up small "C" clips & pins that always seem to find camouflage on shop floor. A refrigerator magnet it ain't. Let the wife try it on her fridge just after unpacking & she couldn't get it off the fridge. Had to carefully slide it to the edge & pry off. I would not want this near any of today's electronics. Well worth the cost just in recovering dropped small parts.
GREAT BUT DANGEROUS IF MISHANDLED.

I'm no magnet expert but this is a seriously strong magnet. If you stick it to something you will likely have a hard time getting it off, and may well scratch paint, etc. in the process. I put it on the side of my breaker box for safekeeping and the breakers started buzzing(!!!) so I moved it elsewhere.
This will be great for anyone needing to find tools, nails/screws, clear shavings, etc. but it's probably too strong (and a little dangerous) for most people.
Be careful where you put it - not near CRTs, hard drives (unless you are purposely wiping them), pacemakers, VHS tapes, etc.

Not for kids. Not for the fridge.

Good grief, this thing is serious. I used it to fix some other ferromagnets. While playing with it i broke it in half. While playing with those two halves i broke one over my finger in between the halves. Now i have 3 magnets that still do some serious work.
Very powerful for its size. My husband is supervising ...

Very powerful for its size. My husband is supervising a bridge repair & tools sometimes get knocked into the river. So far, this magnet (tied to 90lb. para cord) has been able to retrieve everything that's fallen in, even against the current. I've seen them trying to find a tool that it can't lift.
