Review on MOOB Magnetic Key Ring Holder: Wall-mounted, No Drilling, Adhesive Hooks [2 Pack] - Convenient Key Rack Organizer for Wall/Door by Theresa Mcdonald

Amazing little wood coated magnetic devices. They easily hold 1/2 lb, but as soon as you get a heavier item it slips off. I think it will also depend on the texture and shape of the heavier item. If it's smooth it will slip, if it's textured it will hold. If it's round, it should be light. Anyway, the sticky foam pad seems to work well in an air conditioned space. I plan to use it on our RV and know that the adhesive disc will fail in the high temperatures our RV is exposed to during the summer months when stored outside. Do I intend to remove the adhesive disk and use another medium that is more suitable for my application? They have so many uses and are only limited by your imagination. I see that I will invest in many others. Thanks very much!
