Lightweight, compact, and impressively strong for their size, but also relatively fragile.As advised by many other reviewers, these are highly susceptible to cracking or chipping. However, this is not unusual for magnets of this type.I can see how some people have experienced them snapping altogether. As they're not very thick or dense, they need to be handled carefully. SLIDE them apart from each other. Don't pull them off directly, especially not by the ends. Be just as cautious when adjusting them on whatever surface they've been placed.I've managed to keep all of them intact despite some minor chipping on the corners and edges of a few of them. But in my case, the breakage of tiny pieces is due primarily to their application and repeated adjustments before finalizing their placements.I've used them to supplement the resistance inside an old elliptical trainer for which I can no longer find a replacement console. As I can no longer control the resistance electronically, to compensate, I've stacked these bars along the inside of the existing break assembly, and with some experimentation, I've been able to to get about 70-80% of the maximum resistance I'd normally get without taking apart any of the mechanism, cutting cables, or forcing any contact with the main flywheel. And that's just with ONE set of these magnets. I could potentially go over 100% of the original maximum by adding a second set.In essence, I've prolonged the lifespan of my machine and saved myself hundreds of dollars. I no longer have real-time control or dynamic programming, but I'm okay with the semi-permanent, medium-difficulty setting. Anything else, I can track on my smart watch.

I have a stacked washer/dryer. Lid of the washer needed to be held up for me to transfer my clothes. The magnets hold it up great now so I can have an enjoyable laundry experience.

If you are planning to hang up a displate with these, forget it.The magnet itself is not strong enough to hold it in place, so I doubt it would be strong enough to hold a hammer like in the pictures.As for the glue, 2 of my magnets just keep falling off the walls.Overall I simply dont recommend wasting your time and money on those.

These are horrible. One broke in 3 pieces, with no effort at all. The two sided tape won't stick to anything. I am returning these.

Very useful for many applications. My power bars hold great with these strong magnets.
