Review on Superior Neodymium Adhesive Tape for Optimal Blackboard Attachment by Darin Marshall

I used these on the Home Intuition heat and air deflectors to help direct my air conditioner in my bedroom. The deflectors had magnets but not strong enough to hold them in place. I tried other magnets but they weren't strong enough. These magnets hold the baffles in place that prevent air from getting between my curtains and my window and out into the room instead! Now I can control the direction the air blows into my room! I read another review that said these magnets are so strong they are difficult to separate and I agree! I had to use a kitchen knife to separate them - and pull really hard! But once you separate them, they work really well! I would advise keeping them away from children who might try to swallow them! They're a little over a quarter taller, but thicker. NOT for toys! Very strong magnets!
