This was a present for my husband. Although it looks good, the mechanism feels clunky rather than smooth, and it is difficult to fit 4 cards into it and have it work properly. It feels too “tight” with 4 cards in and difficult to remove the cards, especially if they are not at the top. Sometimes two or more cards end up on the same “level”. With only two cards in it, he’s just tried shaking the wallet upside down and a card fell out. It’s a great shame as it does look good, but sadly more of a pain to use than a pleasure. Certainly nowhere near as easy to use as the promo film makes out. Please could you let me know what the situation is regarding returning it under the guarantee, given that I had it engraved with his initials....? Many thanks.
