Got these to stop my cat from opening the cupboards and they did just that. I used two per cupboard since my cat has a little strength. Be 100% sure about where you’re placing it because the adhesive sticks really fast and if you have to move it the magnet will come off with part of the adhesive and the other part on the surface.

Very easy to install. Has stayed stuck even with a lot of use. The grab power is great. Don't need more, but if/when I do, these will be tops on the list.
