Bests & Worsts Reviews from Amazon

This will hold during a quake, or pretty much all other types of mishaps. I wish to advise buyers not of a product flaw, there isn't one of those, but of a user-flaw, a human factors issue that comes from using products like this, any products like this. It's an educational issue. If you have shelf mounted valuables you need this. If you have shelf mounted valuabled and grand children, then you really need this, plus supervision of rug rats. THIS IS NOT A PRODUCT FLAW, THIS IS A HUMAN FACTORS ALERT ON HOW TO PROPERLY USE. While these affixed items aren't going to fall on their own there is the possibility that when you go to pick it up (say to dust it off) and it resists (like you should expect), and so you grab it again redoubling your tug. It's at this point, when you apply more force, that it will suddenly release, it's not a gradual stretchy kind of letting go, it's a let go all at once kind of release. So long as you expect that it's not a problem, but if you're not prepared that sudden release could cause you to fumble the proverbial football. So, grab it firmly knowing you are going to apply a steady motion of increasing force and that it's going to release all at once. Note: How this handles is likely to be subject to climate (head,humidity, cold, surface conditions on piece and on shelf, etc). Warn others that go to handle your valuable collectibles.
