Review on Minimalist Aluminum Organizers for Men's Accessories: Automatic Wallets, Card Cases & Money Organizers by Lungogo by Fred Maki

Overall product is good, holds cards well until I use it to store cards with a very smooth surface. These cards pop up when I shake my pop wallet For other cards, it's pretty good and keeps them inside. The eject button is also very tight and sometimes my finger hurts a bit. There are no complaints about the durability.
