Great size and I especially that there isn't a clip to get caught in jeans pocket, unlike another brand I tried. The pattern makes it more interesting than a plain/flat look. Not sure how I can test the RFID protection part so Ill just have to trust their claim. Suggestion for improvement: make it so the cards in the slot stagger. The first and last slots aren't a problem but the middle card ends up the same height as the last so getting it out takes some digging. Thankfully, the slots aren't very tight so that saved my cuticles.
