I recently bought an aluminum wallet and I have to say I have mixed feelings about it. While it's really thin and minimalist, it doesn't quite live up to its promise of blocking RFID. I noticed my cards were still being scanned when I brought my wallet close to the card reader. It serves its purpose of storing multiple cards and cash. It's also a great size for my grandpa who doesn't have to carry a lot of cards around. However, I wish the money clip was a little stronger as it doesn't hold the money securely. All in all, an aluminum wallet is a good option, but not the best in terms of RFID blocking and cash storage.
