Review on MIKEDE 8-Pack Powerful Neodymium Magnets With Double-Sided Adhesive - Ideal For Fridge, Crafts, DIY, Science, Building & Office Projects - Rare Earth Magnets For Strong Grip by Adam Madden

I bought these to shut off fridge/freezer lights on a new french door LG fridge/freezer. These are the thinnest powerful magnets I could find. I used one adhesion dot to hang a magnet inside the freezer - so far the glue seems to hold in the cold damp environment. They are way more powerful than I expected - do be careful trying to re-stack them you could get your fingers pinched hard. Follow the instructions for removing magnets from the stack (here on amazon from the seller) and you won't have any breakage. I don't recommend for sticking them directly to your fridge - they're so powerful you're likely to scratch off any paint or coatings trying to get them off if they're stuck directly onto the fridge door.
