I put one on a bag I made for my Mom. I had already made her a summer one with a button but she wanted a winter one also. I put a snap on it instead of the button and she didn't like it. She had a hard time getting the bag open. She had to pull hard on both sides to get it to open or put her finger nail inbetween the magnet to open. She said it felt like she was going to rip the bag by tugging so hard.
