Keep the magnet, but an important note is missing from the product page!

I myself have tinkered a magnetic bulletin board, as I have bought a picture frame and the rear wall painted with magnetic paint several times. Furthermore I have a picture excited (paper, 120g). Weaker magnets have as yet no chance to keep something.

((Well something that my joy but tarnishes a lot. The magnetic wall should next to my (all-in-one) are directly PC on my desk. The magnet was a hint folder in the stands, that this kind of powerful magnets among other things, should not be used near PCs (safety distance about 1 m). In 'normal' magnet that's probably otherwise not a problem. I can imagine that many people know so little ... for the rest of the ignorant, so like me, it would be very helpful if these and other sämliche warnings were to be found directly on the product page.
The criticism may sound petty, but this notice would have really helped me (I had the whole project equal shelved), because, unfortunately, I have not the ability to hang the wall to another wall, my shared flat is easy to small ...))

Addendum: After I contacted the seller because of this problem, I just got an answer promptly and want this also quote briefly:

"You can also hang these magnets safely to the PC. The
attached safety instructions apply primarily for larger
Magnets, which we also offer. We therefore the whole range
must cover, the safety lie in general. "

So there is no problem in my case. I'm very relieved!
